Paint is made in several levels of base, from white base to medium base, deep base, and neutral base. Each base is designed to accept a certain amount of colour. The addition of colourants or tints can alter the colour and shade of the paint. For instance, adding a dark tint to a white base will cause the base colour to grey slightly. Tinting paint is not something you want to try on your own, as the tinting equipment used is designed to ensure that each gallon of paint gets the same amount of colourant. However, if you have already applied untinted base paint, you can let it dry and then add a new coat of tinted paint.

What You'll Learn
Tinting machines ensure each gallon of paint gets the same amount of colourant
Tinting paint is a complex process that involves ensuring proper tinting, colouring, and dispensing. While technology has improved colour-matching capabilities, the process still relies on the raw materials used, such as colourants, which must be controlled for colour, colour strength, and weight per gallon.
Tinting machines play a crucial role in ensuring consistency in paint colour. These machines are designed to ensure that each gallon of paint receives the same amount of colourant, resulting in uniform colour across different batches. This precision is essential for maintaining the desired colour and coverage for painting projects.
The use of tinting machines has enhanced the accuracy of paint tinting. While there may still be slight variations due to human error or batch differences, modern tinting equipment is highly precise, delivering consistent results down to a tiny fraction of an ounce. This level of accuracy ensures that each gallon of paint meets the specified standards.
Different paint bases, such as white, medium, and deep bases, also come into play when tinting. These bases are designed to accommodate specific amounts of colour, with deep bases intended to be entirely coloured by the tinting machine. The choice of base depends on the desired colour depth, ranging from pastel to medium and deep colours.
By utilising tinting machines and selecting the appropriate paint base, paint manufacturers can guarantee consistent colour across different gallons of paint. This consistency is vital for meeting customer expectations and ensuring a seamless painting experience, eliminating the need for manual mixing on the job site.

Tinting paint yourself can be difficult
Paint is made in several levels of base. A white base, for example, has a lot of white tint and is intended to have small amounts of colour added to create an off-white. A medium base has less white tint and is used to make more colourful colours like pastels. The three primary colours (red, blue, and yellow) will alter the colour and shade of the paint. The primary colours can be used to produce greener or more orange effects, but these are more difficult to achieve perfectly.
The amount of tint present in a paint determines its colour. The more colourant you add, the more likely the paint will be of the desired colour. Since colourants are paint pigments that are concentrated, you only need a little to create a significant difference in colour or tint. However, knowing the exact combination and amount of tint to add can be difficult.
If you are tinting paint primers like Kilz, the process is relatively simple, but getting the desired results can be time-consuming. For example, if you have deep blue latex paint and want a sky blue, you can add white paint to make it lighter and brighter. However, it is difficult to match a specific colour at home.
To tint paint yourself, use swatches to find the change in shade that your base colour will need to undergo. Purchase enough of your chosen base colour to cover the walls or ceiling of the room you are working on, and approximately one-fifth of the volume of the base colour in your desired tint. Remove the lids from the cans of paint and stir thoroughly. Add the tint colour a little at a time, stirring after each addition until the correct shade is achieved.

White paint needs colourant added to the base paint
Paint is made in several levels of base, with white base intended to have small amounts of colour added to create an off-white. A medium base has less white tint and is used to make more colourful colours like pastels. A deep base has no white tint and is intended to be entirely coloured by the squirts of colour from the tinting machine.
White paint, therefore, needs colourant added to the base paint. The amount of colourant added to each base is dictated by the final colour required, the type and opacity of the colourant, and the level of opaque pigment in the base. If too much colourant is added to the paint, it will not perform properly and may not dry.
Paint manufacturers use different bases for different colours. A white base is for lighter colours, a medium base is for mid-tones, and an ultra-deep base is for dark colours. The bases will determine how much tint or pigment will go into the can.
The process of adding colourant to paint involves creating a sample by adding the colourants in the required proportion, using formulas or by eye, and mixing thoroughly at each stage. The sample is then tested and allowed to dry. Colours may darken or lighten after drying, depending on the type of paint. The process is then adjusted as needed, allowing for tint or shade.

Dark colours have a higher pigment content and can be lightened more easily
Tinting paint involves lightening or darkening a paint colour to your desired shade. Paint colours are categorised into three base types: pastel, medium, and deep or dark colours. Dark colours have a higher pigment content, and while they can be lightened, it is a challenging process.
The heaviness of the pigments in dark colours, such as deep umber, black, or grey, makes it difficult to mix them evenly. To lighten dark colours, you must add white to the formula. However, achieving a perfect mix requires patience and thorough stirring. Benjamin Moore introduced tint formula bases, which are pre-mixed in factories, addressing the challenges of on-site tinting.
When lightening or darkening paint, it is advisable to request a sample first. This allows you to test the shade before committing to a large quantity. For instance, if you want a colour that is 50% lighter, you can request a sample, test it, and adjust the percentage as needed before finalising your decision.
It is worth noting that lightening or darkening paint by a significant percentage, such as 75%, may not yield satisfactory results. In such cases, it is often better to choose a new paint colour altogether. Additionally, altering lighter paint colours can be more challenging, as they may appear muddier or less noticeable. Therefore, when lightening dark colours, it is crucial to consider the percentage of change to achieve the desired effect.
In conclusion, while dark colours can be lightened, it requires careful consideration and experimentation. The high pigment content of dark colours makes the process more intricate, and the success depends on finding the right balance of tint and thorough mixing.

Pure black and white paint are challenging to mix
Mixing paint colours is a fun and experimental process, but pure black and white paint can be challenging to mix. The reason for this lies in how paint and light work. Paint gets its colour from opaque particles of pigment that absorb certain colours and reflect others. For example, red paint scatters back red wavelengths and absorbs the others. When you mix paints, they absorb more of the spectrum, resulting in black. However, to get true black, all wavelengths of light must be absorbed, and it is challenging to get paints to absorb all wavelengths.
Mixing complementary colours can get you close to black. For example, mixing red and green, blue and orange, or purple and yellow can create a dark, almost black colour. You can also try mixing equal parts red, blue, and yellow paint to get black. Adding a bit of dark blue paint, like Prussian Blue, can also help achieve a deeper black.
White paint is also challenging to mix, as it serves as a base for other colours. White paint has a lot of white tint and is intended to have small amounts of colour added to create off-whites or pastel shades. It is difficult to get a pure white because of the high amount of white tint already present in the base paint.
Additionally, when mixing paints, it is important to consider the different bases of paint: deep, medium, and white. Deep bases have no white tint and are meant to be entirely coloured by pigment additions. Medium bases have less white tint and are used for more colourful shades like pastels. White bases have a lot of white tint and are intended for off-white colours.
While pure black and white paint are challenging to mix, it is possible to get close by experimenting with different colour combinations and understanding the bases of the paint you are using.

Frequently asked questions
Tinting is the process of adding pigment to a base paint to create a specific colour.
Tinting paint allows you to create a specific colour that matches your desired shade. Paint is made in several levels of base, from white to medium to deep base, and each accepts a certain amount of colour. Tinting ensures a consistent colour throughout the paint.
Tinting paint is best left to professionals as they have the right equipment to ensure consistency. However, if you want to tint your paint at home, you can add several drops of tint to a small quantity of base colour and stir thoroughly. Be careful not to add too much tint at once, as the shade can change dramatically with just a few drops.
It is not recommended to use untinted base paint, especially if you are trying to cover an existing colour. The colour may bleed through, and you may not get the desired shade. If you have already used untinted base paint, let it dry before adding a new coat of tinted paint.
