Colour Red. Everything you need to know

colour red

The colour red is a rich colour with an even richer history. The use of this pigment dates back to ancient Egypt, where it was considered as much a colour of vitality and celebration as it was of evil and destruction. From there, red was a staple hue throughout history, used in ancient Greek murals, on Byzantine clothing to signal status and wealth, and widely applied in all art movements from the Renaissance to modern art.

Red is considered a colour of intense emotions, ranging from anger, sacrifice, danger and heat, to love, passion and sexuality.

You see shades of red on screens almost every day. There are, within the range, from pure red to an infinite number of different shades: pinkish reds, dark reds, reds, reds, garnets, passion reds…

The reason is that the colour red has a remarkable nature. The user interface designer uses the red colours to attract attention.

Not all reds are the same. Apart from light and dark shades of red, there are two types of red: Tomato red and cherry red

Yellow-based reds are “tomato” reds. Blue-based reds are “cherry” reds. Some say that men are more attracted to tomato reds: women to cherry reds.

Context is everything when using red. For example, when red is placed on a black background, it glows with an otherworldly fire; on a white background, red appears somewhat duller; in contrast to orange, red appears lifeless. Notice that the red square appears larger on the black.
