## How color mixing works in each color space

**RGB blending** is the simplest approach. Each of the three channels (Red, Green, Blue) is interpolated independently between the two source colors. At a 50/50 mix of red and blue, you get a mid-point purple. RGB blending is predictable but can produce desaturated or muddy results in the middle of transitions because of how human vision perceives brightness.

**HSL blending** interpolates through the hue wheel, saturation, and lightness separately. This produces more vibrant transitions because the algorithm takes the shortest path around the hue circle. Blending a warm orange and a cool blue in HSL space will pass through rich purples rather than the grayish mid-tones you would see in RGB.

**LAB blending** (CIE L*a*b*) works in a perceptually uniform color space, meaning equal steps in LAB values correspond to equal perceived differences in color. This color space was designed to match human vision. Blending in LAB space produces the most visually "natural" transitions and avoids the brightness spikes that can occur in RGB mixing. It is the preferred method for color science, print production, and accessibility work.

## When to use each color space

- **RGB**: Use when matching digital display output, working with CSS `rgb()` values, or when you need deterministic channel-level control.
- **HSL**: Use when designing color themes, generating gradients with vivid intermediate steps, or working with palettes where saturation and lightness must stay consistent.
- **LAB**: Use when you need perceptually uniform results, when producing accessible color palettes with consistent contrast ratios, or when preparing colors for print workflows where absolute perceptual accuracy matters.

## How to use

1. Click the Color A picker and choose your first color.
2. Click the Color B picker and choose your second color.
3. Drag the Mixing Ratio slider to set how much of each color contributes. Moving left gives more of Color A; moving right gives more of Color B.
4. Select a color space: RGB, HSL, or LAB. The mixed result updates instantly.
5. Copy the HEX value using the Copy HEX button, or note the RGB and HSL values shown in the result grid.

## Understanding the gradient preview

Above the result swatch, the tool shows a gradient strip running from Color A through the mixed result to Color B. This gives you a visual sense of the full range of the blend and helps you spot the character of each color space. In RGB mode the gradient may appear to dip through unsaturated tones in the middle; in HSL and LAB modes the transitions tend to stay more vivid throughout.

## FAQs

**Q:** Why does LAB blending look different from RGB blending?


**A:** LAB is a perceptual color space that maps colors the way human eyes perceive them, not the way displays encode them. A 50/50 LAB blend will often look brighter or more saturated than the equivalent RGB blend because LAB accounts for the non-linear way our vision processes luminance.


**Q:** Can I enter my own HEX code instead of using the color picker?


**A:** The native color picker inputs accept typed hex values in supported browsers. Click the hex display next to the picker and type your value directly.


**Q:** Why does the mixed color look gray or desaturated in RGB mode?


**A:** When two colors that are far apart on the color wheel are blended in RGB, the intermediate values often land in the low-saturation center of the RGB cube. Switching to HSL or LAB mode typically produces a more vibrant result.


**Q:** What is the mixing ratio?


**A:** The slider sets how much of Color B is in the result. At 0% you get Color A unchanged; at 100% you get Color B unchanged. At 50% both colors contribute equally.


**Q:** Is the HEX output in uppercase?


**A:** Yes. The tool outputs uppercase 6-digit HEX codes, for example `#3B82F6`. This format is compatible with all CSS color properties and design tools.


**Q:** Can I use this for CSS gradients?


**A:** Yes. Copy the HEX values at different slider positions to build the color stops of a CSS `linear-gradient`. Using LAB blending to pick midpoints gives you perceptually uniform gradients.
