IconVault's Color Mixer blends two colors with an adjustable weight and blend mode, showing the result in HEX, RGB and HSL plus a gradient of intermediate mix steps between them. Dial the ratio until you hit the exact tint, shade or in-between tone you need. It is free and runs fully in your browser.

Mixing is the fastest way to build tints (add white), shades (add black) and tones (add gray) that stay consistent with your base colors. The step preview is perfect for generating button hover states, gradient stops and data-viz scales. Trial use is recorded only when you copy a value.
