blue and red make what color
When blue and red colors mix together, they make violet. Here’s a detailed explanation of how blue and red combine to make purple:
Additive Color Mixing:
The mixing of colors can be understood through the concept of additive color mixing, which involves combining the light of different colors. In additive color mixing, the primary colors are red, green, and blue (RGB). By varying the intensity of these primary colors, many other colors can be created.
Primary Colors:
Blue and red are the two primary colors in the additive color model. Blue is associated with shorter wavelengths of light, while red is associated with longer wavelengths. When pure blue and pure red light are mixed together, they both contribute their respective wavelengths to the resulting color.
Subtractive color mixing:
Blue and red are also primary colors in the subtractive colour model, commonly used in the mixing of paint, ink, and dye. In subtractive color mixing, the primary colors are cyan, magenta, and yellow (CMY). When blue and red pigments or dyes are mixed together, they absorb certain wavelengths of light, resulting in different color perceptions.
Combination of blue and red:
When blue and red colors are mixed together, they overlap in the middle range of the visible spectrum. Blue light has shorter wavelengths toward the violet end, while red light has longer wavelengths toward the orange end. Overlapping wavelengths in the middle range, which correspond to violet, are seen when blue and red light are combined.
Color Perception:
Our eyes and brain interpret combinations of different wavelengths of light as specific colours. When blue and red light mix, our visual system processes the combination of their wavelengths and perceives the resulting colour as violet.
It is important to note that the specific hue and intensity of the blue and red used in the mixture can affect the resulting hue of purple. Different variations of blue and red, such as lighter or darker hues, can give rise to different shades of purple, ranging from deep purple to more reddish or bluish purple.
In summary, when blue and red are mixed together in a composite colour model or combined as pigments in a sub-chromatic colour model, they create the color violet. The perception of violet is the result of overlapping wavelengths of blue and red light.
