Red is one of the most powerful and vibrant colours, easily attracting attention. It is often seen as a symbol of emotion, passion and energy. Red is often a symbol of love, romance and strength. It is therefore not surprising that the red rose is one of the most well-known symbols of love. In addition, the use of the colour red increases adrenaline levels, resulting in a fast heartbeat and increased energy levels.
On the other hand, red is often associated with power and strength. It is found in the national flags of many countries and has been used throughout history in military and combat dress. It also has a prominent role in warning signs, as it is easily visible. For example, in traffic lights or on prohibition signs. The colour red therefore carries many different emotions and meanings and can have different symbolism in different cultures.

What is the colour of red?
The colour of red depends mainly on the wavelength of the light. In the visible light spectrum, the red colour generally falls in the wavelength range 620-750 nanometres. The hue of the colour can also vary depending on various factors such as the intensity of the illumination, the material properties of the colour, or the contrast of the background. In addition, colour perception can also be subjective, as colour vision can vary from person to person.
How is the red colour colour mixing possible?
There are several ways to mix the colour red, depending on the colour scheme you use:
1. **Additive colour mixing (RGB):** In additive colour mixing, the red colour is achieved by maximising the red component. In this system, the red colour is created independently and no other colours need to be mixed. In the RGB model, the values of red are R=255, G=0, B=0.
2. **Subtractive colour mixing (CMYK):** In subtractive colour mixing, the red colour is created by mixing cyan and yellow inks. Mixing the two colours together produces the red colour because these dyes absorb (subtract) the Green and blue light, leaving only the red light visible.
3. **Mixing pigments:** When it comes to dyes, you can mix the red colour with other colours in different proportions. For example, mixing orange and pink can also give red tones, but the most commonly used method is to use the basic red pigment on its own.
