Reference table
| Setting | What it changes | Useful check |
|---|---|---|
| Hue family | Limits the hue-angle range | Color perception also changes with saturation and lightness. |
| Saturation | Controls color intensity | Muted colors use lower saturation values. |
| Contrast ratio | Compares relative luminance | Test final text and background pairs in context. |

Quick knowledge check
What is the best first check before using generated output?
Microlearning guide
Randomness can cluster
A fair random process can still create streaks, repeated patterns, or uneven-looking small samples.
Uniqueness changes the pool
Sampling without replacement prevents repeats but also reduces the remaining eligible choices after every pick.
Use the right scope
These are browser utilities for planning, learning, creative work, and test data—not audited draws or high-stakes systems.

Frequently asked questions
How are colors generated?
The tool randomly chooses HSL values inside the selected hue, saturation, and lightness ranges, then converts them to RGB and HEX.
Does the contrast check guarantee accessibility?
No. It is a quick numerical reference. Real accessibility also depends on font size, font weight, UI states, and applicable standards.
Can I generate only warm or cool colors?
Yes. Choose Warm or Cool in the hue family selector.
Why can two colors look similar?
Random values can cluster, especially inside narrow hue and saturation ranges.
Does the tool change the website theme?
No. Generated colors appear only in the result palette and are not applied to the site interface.
