Paint bases are an essential component of the painting process, as they provide the foundation for specific colours. While clear bases are used to create darker shades, white bases are used for the lightest colours. The amount of titanium dioxide in a paint base determines its opacity and coverage, with light bases being more opaque than medium bases, and white bases having the most coverage. Medium base paints have a moderate tinting capacity and are used to achieve mid-tone or pastel colours, while deep base paints can handle a larger amount of colourant to produce darker colours and have higher tinting capacity.
| Characteristics | Values |

| Opacity | Light bases are more opaque than medium bases |
| Titanium dioxide content | White bases have the most titanium dioxide, followed by light bases, medium bases, and dark bases |
| Colour | Medium bases are used for mid-tone or pastel colours; deep bases are used for dark or very bright colours |
| Use case | Medium bases are used for common painting requirements and can be used for both interior and exterior painting; deep bases are used where decoration and visual impact are important |

Medium-base paints are used for mid-tone or pastel colours and can be used for both interiors and exteriors
Paint is made up mostly of its base. Paint bases are offered in a variety of colours, including white, pastel, light, medium, deep, and clear. The base used determines the final colour of the paint, as well as its resistance to dirt and stains and its durability under intense scrubbing.
Medium-base paints are used to create mid-tone or pastel colours. They can be used for both interiors and exteriors and are commonly used for general painting requirements. They are more opaque than light bases but less opaque than white bases. They also have less white pigment than light bases, which means they can produce deeper colours.
Medium-base paints are suitable for use on both interior and exterior surfaces. They are often used as an all-purpose paint due to their versatility and ability to cover previous surface colours effectively. While they can be used on their own, they can also be mixed with other colours to create a range of mid-tone shades.
When choosing between a light or medium-tintable base, it is important to consider the specific painting project and seek advice from a professional if needed. A light base will typically provide more opaque coverage, but a medium base can create a deeper colour. Additives such as mildewcides and thickeners can also be incorporated into medium-base paints to enhance their performance and protect against mould growth, drips, and spatters.
Overall, medium-base paints are a versatile option that can be used to create a range of colours and are suitable for a variety of applications, making them a popular choice for both interior and exterior painting projects.

Deep-base paints are used for darker shades and are suitable for decoration and visual impact
Paint is made up mostly of its base. Paints are first created in the form of paint bases with a few basic colours before being tinted. The base of a paint determines how resistant it is to dirt and stains, as well as its durability under intense scrubbing.
In contrast, medium-base paints are used as an all-purpose paint for interior and exterior painting. They can be used to create mid-tone or pastel colours. They have a higher opacity than deep-base paints and can be used to create a deeper colour.
It's important to select the right base paint for your walls, depending on the specific wall types and visual requirements.

Titanium dioxide content: white bases have the most, light bases are more opaque than medium bases, and dark paints have the least
The amount of titanium dioxide in a paint base determines how well it conceals the previous surface colour. White bases contain the most titanium dioxide and provide the fullest coverage. Light bases are more opaque than medium bases, while medium bases can create deeper colours than light bases. Dark paints, on the other hand, are produced from bases containing little to no titanium dioxide, resulting in less opaque coverage.
White bases are typically used for lighter colours, while medium bases are suitable for mid-tones. Deep bases are used for dark and very bright colours, such as neon or deep red. These bases have a very low percentage of white pigments, as the end requirement of the paint application demands a deep or dark shade.
The level of opacity desired for a specific painting project will determine whether a light or medium tintable base is more suitable. While light bases offer more opaque coverage, medium bases are more versatile and can be used for both interior and exterior painting. They are commonly used for general painting requirements.
The difference in opacity between light and medium bases is due to the varying concentrations of titanium dioxide. Light bases contain more titanium dioxide than medium bases, allowing them to better hide the previous surface colour. This property of titanium dioxide makes it an essential consideration when selecting the appropriate paint base for a specific project.
In summary, the titanium dioxide content in paint bases plays a crucial role in the opacity and coverage of the paint. White bases have the highest titanium dioxide content, followed by light bases, medium bases, and dark bases with the least. This gradient of titanium dioxide concentration directly influences the opacity and coverage of the resulting paint, impacting the final colour and its ability to conceal underlying surfaces.

Deep-base paints are used for very saturated colours, while medium-base paints can create deeper colours than light bases
Paint bases are graded into types based on their objective and colour. Clear bases are used to create darker colours, while white bases make the lightest colours. A light base creates a lighter colour than a medium base.
Deep-base paints are used for extra saturated colours after application. They feature higher concentrations of neutral or dark pigments, which are suitable for giving a foundation for rich and saturated hues in the final application of paint. These paint bases have a very low percentage of white pigments. The darker the colour of the paint, the deeper the base of the paint will be.
Medium-base paints are used as an all-purpose paint that can be used for both interior and exterior painting and is heavily used for common painting requirements. They are used to create mid-tone or pastel colours. A medium base can create a deeper colour than a light base.
The amount of titanium dioxide in a paint controls how well it hides the prior surface colour. White bases have the most titanium dioxide with the fullest coverage, even though light bases are more opaque than medium bases. Less opaque dark paints are produced from bases containing little to no titanium dioxide.

Medium-base paints are an all-purpose option, whereas deep-base paints are used where decoration is important
Paint bases are graded based on their objective and colour. Paint bases range from clear to deep, creating paint colours to accommodate any painting project. A tintable paint base is used to form the foundation for a particular colour.
Medium-base paints are used as an all-purpose paint and can be used for both interior and exterior painting. They are heavily used for common painting requirements. Medium-base paints can be used to obtain mid-tone or pastel colours. They can also be used to create a deeper colour than a light base.
Deep-base paints, on the other hand, are used where decoration and visual impact are important. They are used to produce deep or dark shades when tinted with colourants. They feature higher concentrations of neutral or dark pigments, providing a foundation for rich and saturated hues in the final application of paint. Deep-base paints result in extra saturated colours after application.
The amount of titanium dioxide in a paint controls how well it hides the prior surface colour. Light bases are more opaque than medium bases, and white bases have the most titanium dioxide with the fullest coverage. Dark paints, which are created from bases with little to no titanium dioxide, provide less opaque coverage.
Different retailers will use different colourant systems. A white base is used for lighter colours, a medium base for mid-tones, and an ultra-deep base for the bottom of the card colours.
