What is the difference between HEX and RGB color formats?

HEX is a shorthand for RGB in hexadecimal notation. #FF0000 is identical to rgb(255, 0, 0) — both represent pure red. HEX is popular in CSS for its brevity, while RGB is easier to read and manipulate mathematically.

What is HSL and when should I use it?

HSL stands for Hue, Saturation, Lightness. It is more intuitive for human eyes than RGB — you can easily create color variations by adjusting the lightness or saturation while keeping the same hue. HSL is excellent for generating consistent color palettes in CSS.

Can I use this to get Tailwind CSS color values?

Yes. Tailwind uses HEX and RGB values for its color palette. You can also extract HSL values for use with CSS custom properties and Tailwind's arbitrary values syntax.

What is the difference between #RGB and #RRGGBB?

#RGB is a shorthand where each digit is doubled — #F00 is equivalent to #FF0000. The 3-digit shorthand only works when both digits of each channel are identical.
