HSLider

About HSLider
Targeted at developers using CSS, this Dashboard widget uses HSL sliders and plain ol’ text fields to tweak colors. Copy your new color as valid CSS (hex, RGB, or HSL) with a single click.

- Liberal input: Accepts 3- or 6-character hex strings with or without the leading hash (“#”) and pretty much anything for HSL and RGB so long as it finds 3 numbers in there.
- Strict output: Copy valid CSS to the system pasteboard with a single click. Hex values are copied uppercase or lowercase, shortened or not, according to your preference.
- Keyboard capable: Use the up and down arrow keys to adjust individual HSL and RGB values one click at a time (or try Option + Arrows to take bigger steps).
