When it comes to art, selecting the right paint can be a challenge, especially with the variety of tubes and containers available. Reading paint tube labels is therefore essential to understanding the paint's properties and ensuring you get the desired results. One of the key features on a paint tube label is a series of squares that indicate the level of transparency or opacity of the paint. This is particularly important for artists who want to produce specific colours and effects in their work. So, what do these squares on the paint tubes mean, and how do they help artists make informed choices?
| Characteristics | Values |
|---|---|
| Opaque | Black square |
| Transparent | Clear or white square |
| Semi-transparent | Square with diagonal line, bottom half black |
| Semi-opaque | Square with diagonal line, half white/half black |

The square's colour indicates the paint's level of transparency
When it comes to art, selecting the right paint colour is crucial. However, choosing the right paint involves more than just the colour name or shade. The squares on the paint tubes are one of the many ways to understand the paint's characteristics. These squares indicate the paint's level of transparency, with different colours representing varying degrees of opacity.
The square's colour plays a significant role in communicating the paint's transparency level. A black square, for instance, denotes that the paint is opaque. This means the paint will not allow light to pass through, resulting in a more solid appearance. On the other hand, a clear or white square indicates transparency. This type of paint will allow light to pass through, creating a more translucent effect.
Additionally, there are squares that fall between these two extremes, indicating varying levels of semi-opacity or semi-transparency. For instance, a square with a diagonal line through it and the bottom half filled in black signifies semi-transparent paint. This paint will allow some light to pass through while still providing some level of opacity. Similarly, a white box with a diagonal line indicates semi-transparent paint, and a diagonally divided half white and half black box represents semi-opaque paint.
The squares on the paint tubes are a quick and convenient way to understand the paint's transparency level, helping artists make informed decisions about their artwork. It is important to note that different manufacturers may use different symbols or codes to indicate transparency and opacity levels, so it is always beneficial to refer to the paint tube's label for specific information.

Black squares denote opacity, while clear squares indicate transparency
When it comes to paint tubes, the squares denote the level of transparency of the paint inside. While there is no set standard, with different manufacturers using different visual codes, the squares are a common way to indicate transparency and opacity. Black squares denote opacity, while clear squares indicate transparency. A black square means the paint is totally opaque, while a clear or white square means it is transparent.
A square with a diagonal line through it and the bottom half filled in black indicates a semi-transparent paint. This is also sometimes denoted by a half white/half black square. Some manufacturers use a white square with a diagonal line through it to indicate semi-transparency, while others use a black and white square.
Winsor & Newton, for example, uses a square symbol that's filled in according to the paint's transparency. The more filled in the square is, the more opaque the paint is. This is a simple way to denote opacity, with a filled-in shape indicating a higher level of opacity.
Other manufacturers use lettering, with 'T' for transparent, 'ST' for semi-transparent, 'O' for opaque, and 'SO' for semi-opaque. Some simply write out 'Opaque' or 'Transparent'.

A square with a diagonal line and a black bottom half means semi-transparent
When it comes to paint tubes, the little square found on the packaging indicates the level of transparency of the paint. While different manufacturers use different visual codes, a general rule is that a filled-in shape denotes opacity, while a blank shape indicates transparency.
Winsor & Newton, for instance, uses a square symbol that corresponds to a paint's transparency. A black square on a Winsor & Newton paint tube indicates that the paint is opaque, while a white square means the paint is transparent.
Similarly, Amsterdam uses a square with a diagonal line through it and a black bottom half to indicate that the paint is semi-transparent. This is similar to the system used by other manufacturers, where a white square with a diagonal line through it means semi-transparent, and a diagonally divided half white/half black square indicates semi-opaque.
It is important to note that there is no standard system for indicating the degree of opacity and transparency in paint. Different manufacturers will use different visual codes or symbols to convey this information. Therefore, it is always a good idea to refer to the key or chart provided by the manufacturer to understand the specific symbols and codes used on their paint tubes.

Squares are used to indicate the paint's lightfastness
When it comes to paint tubes, squares are used to indicate the paint's opacity or transparency, which is closely related to its lightfastness. Lightfastness refers to how resistant the paint is to fading when exposed to light. While some paint brands use a star rating or a letter and number combination to indicate lightfastness, others use squares to denote opacity and transparency, which in turn give an indication of lightfastness.
Opaque paints, which offer greater resistance to fading, are indicated by a black square. Transparent paints, which are less resistant to fading, are denoted by a white or clear square. A square with a diagonal line through it, with the bottom half in black, indicates that the paint is semi-transparent, while a square with a diagonal line and the top half in white indicates semi-opaque paint. The number of squares or the shape of the square may vary depending on the manufacturer, but generally, a filled-in shape indicates higher opacity, while a blank shape suggests higher transparency.
The use of squares to indicate opacity and transparency is not standardised across paint manufacturers. Some brands, such as Winsor & Newton, use a square symbol to represent transparency, with the square being filled in to varying degrees to indicate the level of opacity. Other manufacturers, like Golden, use hand-painted swatches of the colour on the tube or container with black bars to indicate opacity.
It is important to note that the colour name on a paint tube may not always accurately represent the actual colour of the paint. Manufacturers often choose marketing names that are catchy and appealing rather than using the chemical names of the pigments, which may be unattractive or difficult to pronounce. Therefore, reading the paint tube labels and understanding the symbols, such as the squares indicating opacity and transparency, can help artists make more informed choices about the paints they select for their creations.

The paint's name is often misleading
When it comes to paint names, it can be misleading to rely solely on the name to determine the colour. While some names may provide an accurate description of the colour, others may be vague, unusual, or even bizarre. For instance, "Raspberry Blush" may evoke a cosmetic product, while "Dead Salmon" and "Elephant's Breath" are certainly unique choices. Some names are more ambiguous, like "Lauren's Surprise" and "Julie's Dream", leaving one to wonder who these people are and what their surprises or dreams might entail.
The challenge of naming hundreds of paint colours may lead to some creative but confusing choices. Food names, for instance, can be tricky; while some, like "cherry red" or "chocolate brown", effectively describe colours, others like "Nacho Cheese" may be less appealing as wall colours. Other names can be downright aggressive, like "Churlish Green", which refers to an archaic term for a peasant, or just plain odd, like "Broccoli Brown", a colour that hopefully no one has ever encountered in their vegetables.
Paint names can also be misleading when it comes to the ingredients used. A tube labelled "Cadmium Red Hue" contains no cadmium but is instead an imitation of the colour using different, safer, and more affordable ingredients. This can be important for health and safety reasons, as some paints contain hazardous elements like lead or poisonous cadmium. Knowing the ingredients is crucial for understanding potential risks and ensuring safe handling and use.
The colour's appearance, transparency, and opacity are also essential factors that may not be accurately conveyed by the name. For example, two paints, Cadmium Orange (Hue) and Pyrrole Orange, may appear identical in colour, but their ingredients differ, resulting in varying levels of transparency. Thus, relying solely on the name can be misleading, and it is crucial to read the labels and understand the specific properties of the paint.
In conclusion, while paint names can be fun and creative, they may not always accurately represent the colour, its ingredients, or its properties. To make informed choices, it is essential to look beyond the name and carefully read the labels, considering factors such as the manufacturer, ingredients, transparency, opacity, and health and safety information provided.
