Frequently Asked Questions

How do I convert HEX to RGB?

Split the six digits into three pairs and read each as a hexadecimal number. #4F46E5 is 4F = 79, 46 = 70, E5 = 229, giving rgb(79, 70, 229).

What is HSL good for?

Adjusting colours predictably. Hue sets the colour, saturation its intensity, lightness how light or dark it is. Building a palette by varying lightness at a fixed hue is far easier in HSL than in HEX.

Is the CMYK conversion accurate for printing?

It is a straightforward mathematical conversion, which is fine for a rough idea. Real print work needs an ICC profile conversion for the specific press and paper, since CMYK cannot reproduce every RGB colour.

What is the difference between HSL and HSV?

They differ in the third component. HSL lightness runs from black through the pure colour at 50% to white at 100%. HSV value runs from black to the pure colour at 100% and never reaches white without dropping saturation.
