Which input formats are supported?
You can choose RGB/RGBA, HEX/HEXA, or HSL/HSLA in the format selector.
Does it accept short HEX values?
Yes. Values such as #0FA and #0FA8 are expanded internally to full-length format.
How do I provide alpha/transparency?
Use alpha between 0 and 1, or percentages between 0% and 100%, depending on input style.
When do I get an invalid color error?
When channels are outside valid ranges, such as RGB outside 0-255 or HSL saturation/lightness outside 0-100%.
Is conversion done on a server?
No. All processing happens locally in the browser.
