Features & Default Keymaps:

Picking Colors:

By default:

h and l will increment the color slider value by 1.
u and i / a and d / A and D will increment the color slider value by 5.
s and w / S and W will increment the color slider value by 10.
o will change your color output
Number 0 to 9 will set the slider at your cursor to certain percentages. 0 sets to 0%, 9 sets to 90%, 5 sets to 50%.
H sets to 0%, M sets to 50%, L sets to 100%.

Multiple Sliders:

By default:

If your slider is on the 4th line (the same line as the color output preview), when you increment / set a color value, it will apply that change to all 3 sliders above it.
gu will select the 1st and 2nd sliders, gd will select the 2nd and 3rd sliders, gm will select the 1st and 3rd sliders.
Press x will deselect the slider group.

Manual Numeric Input:

If you press n, you can press number keys to input the color value manually for individual sliders or slider group. If you press any key that is not a number key, it will execute that key as normal.
For example: if you want to input 15 on the 1st slider: move your cursor to the 1st slider, press n then press 15. Then you can press k to move on to the next slider. The slider values will update as you type out the numbers.

Converting Colors (RGB/HEX/HSL)

When your cursor is on a corlor, use :PickColor to open up the picker, then press o to change the output type to RGB/HEX/HSL. Press Enter and the color under your cursor will be converted.

Transparency Mode

Press t to toggle Transparency Slider. While this mode is active, you will only be able to output the color as rgba() or hsla(). If you want to output as HEX, press t to get out of Transparency Mode, and you'll be able to press o to output your color as HEX.
