Paint Color Mixer
Blend 2-4 colors with custom mixing ratios and preview the result instantly. Get HEX and RGB values for your mixed color.
Quick Answer
Select your colors, adjust the mixing ratios, and click Mix to see the blended result. This tool uses weighted RGB averaging to simulate color blending. The result includes HEX and RGB values you can use in any design application.
Mix Your Colors
Choose colors and set their ratios, then click Mix.
About This Tool
The Paint Color Mixer is a digital tool that lets you blend two to four colors together using custom mixing ratios and instantly preview the resulting color. Whether you are planning a home painting project, creating a design palette, or experimenting with color combinations, this tool gives you a quick visual approximation of what your blended color will look like along with exact HEX and RGB values.
Color mixing is both a science and an art. When you combine colors, the result depends on the mixing system being used. Digital screens use additive color mixing based on the RGB (Red, Green, Blue) model, where light of different wavelengths combines to create new colors. Physical paint uses subtractive color mixing, closer to the CMYK (Cyan, Magenta, Yellow, Key/Black) model, where pigments absorb certain wavelengths and reflect others. This tool uses weighted RGB averaging, which provides a useful approximation for both digital and physical color blending scenarios.
How Weighted RGB Mixing Works
Each color is represented by three values: red, green, and blue, each ranging from 0 to 255. When you set mixing ratios, the tool calculates a weighted average for each channel. For example, mixing #FF0000 (pure red) and #0000FF (pure blue) at a 50:50 ratio yields #800080 (purple), because the red channel averages to 128, the green stays at 0, and the blue averages to 128. Adjusting the ratios shifts the result toward the dominant color. A 75:25 red-to-blue ratio produces #BF0040, a red-dominant purple.
This method is straightforward and predictable, making it excellent for designers and artists who need quick color previews. However, it is worth noting that physical paint mixing can produce different results due to the chemistry of pigments, the opacity of the paint, the number of coats applied, and the surface being painted. Cadmium reds mixed with phthalo blues, for instance, can produce more muted purples than a digital tool might suggest because of how those specific pigments interact at the molecular level.
Practical Applications
Home painters frequently use this tool to preview what a custom-mixed color might look like before purchasing additional paint. If you have leftover cans of two colors and want to combine them, input both hex codes (which you can find on the manufacturer's website or by scanning with a color identification app) and set the ratio based on how much of each you have. Interior designers use it to test color harmonies for rooms, ensuring that wall colors, trim, and accent pieces work together visually before committing to a palette.
Digital designers and web developers use the mixer to generate intermediate colors for gradients, button hover states, or palette variations. By starting with a brand's primary colors and mixing them at different ratios, you can create a cohesive extended palette without guessing at hex values. Artists exploring color theory can visualize complementary, analogous, and split-complementary mixes without wasting paint.
Tips for Better Results
When mixing paint physically, always start with the lighter color and gradually add the darker one. Dark pigments are much stronger than light ones, so a small amount of black or dark blue goes a long way. Mix thoroughly to avoid streaks, and test on a small area or swatch card before committing to a full wall. Keep in mind that paint colors often look different when dry than when wet, and natural versus artificial lighting can dramatically change the perceived color. This tool helps narrow your choices digitally before you invest time and materials in physical mixing.
