Darken or lighten any hex color — generate shades & tints instantly
A shade is created by adding black to a pure color, making it darker. A tint is created by adding white to a pure color, making it lighter. In design, shades create depth and shadows, while tints create highlights and softness.
Convert the hex to RGB, then multiply each channel by (1 - percentage/100) to blend toward black (0,0,0). For example, a 20% shade of #3B82F6 blends 80% of the original with 20% black, resulting in a darker blue.
Convert hex to RGB, then interpolate each channel toward white (255,255,255) using the formula: channel + (255 - channel) × percentage/100. A 30% tint moves the color 30% closer to pure white.
Shades and tints are essential for creating color palettes, hover states, borders, shadows, gradients, and accessible contrast ratios. They help maintain visual hierarchy without introducing new hues.
A tone is created by adding gray (both black and white) to a color, which reduces its saturation/chroma. Shades darken, tints lighten, and tones mute the color. Our calculator focuses on shades and tints for pure darkening/lightening.
