How Color Mixing Works

Color mixing follows two fundamentally different systems. Additive mixing (light, screens) combines red, green, and blue (RGB) — mixing all three at full intensity produces white. Subtractive mixing (paint, ink) combines pigments that absorb certain wavelengths — mixing all primary colors produces a dark brown or black. This calculator supports both models.

RGB Color Mixing (Additive)

In the RGB model, each color is defined by three values from 0-255 representing red, green, and blue light intensity. Mixing two RGB colors averages (or otherwise combines) their channel values. Red (255,0,0) mixed with blue (0,0,255) produces magenta (128,0,128) at equal proportions. The calculator shows the resulting color in real time as you adjust the mix ratio.

Paint Color Mixing (Subtractive)

For physical pigments, the primary colors are cyan, magenta, and yellow (CMY) — not the red, yellow, blue taught in elementary art classes (though RYB is a useful simplification). Mixing yellow and cyan paint produces green. Mixing magenta and yellow produces red-orange. The calculator's subtractive mode accounts for how pigments absorb and reflect light.

Hex Color Codes

Web colors are typically expressed as hex codes — six-digit hexadecimal values like #FF5733. The first two digits represent red (FF = 255), the middle two represent green (57 = 87), and the last two represent blue (33 = 51). The calculator accepts hex input and converts between hex, RGB decimal, and HSL (hue, saturation, lightness) formats.

Practical Applications

Interior design: predicting the result of mixing two paint colors before buying. Web design: finding complementary colors and creating harmonious palettes. Art: understanding how pigment combinations will appear on canvas. Photography and video: adjusting white balance and color grading. The calculator helps in all these contexts by providing a visual preview of the mixed result.

Color Harmony

Colors that work well together follow predictable patterns on the color wheel: complementary (opposite colors like blue and orange), analogous (adjacent colors like blue, blue-green, and green), triadic (three equally spaced colors like red, yellow, and blue), and split-complementary (a color plus the two colors adjacent to its complement). The calculator can suggest harmonious palettes based on your starting color.
