I work with CSS files. Sometimes I want a HEX color slightly darker or brighter than an existing color. From your text editor, select something like 4E80B3 and press Ctrl+Alt+Shift+NumpadAdd (brighter) or Ctrl+Alt+Shift+NumpadSub (darker). The 6 characters will be replaced with the new color.



Can be improved:
* Does not check limits, so it messes up if you try to brighten FFFFFF or darken 000000.
* Would be great if the selection was not lost after pressing the keys, this way you could press them several times.
* I multiply by 1.1 or 0.9 to change the brighness. This is not very good, because it makes impossible to brighten black. Better would be use +10 and -10 for red, and adjust green and blue so the proportion to red is kept.
* A better way would be to show a brightness slider to adjust the color with a GUI.

This is useful, a good idea. Here is a little mod, which keeps the selection, saturates at 00 or FF, does not have unchangeable values, and always produces two-digit hex values (00...0F). Experiment with the increment/decrement functions.

Wow thanks! That's much more clean and organized.

These formulas should compensate the lack of change with dark colors:



(gives increments close to 10 units up or down)



So now it works even with 000000 and FFFFFF.

If someone wants to adjust the increment: the *10 is responsible for the increment when we have dark colors, and the 1.05 and 0.95 for the bright colors. For a smaller step you can try using *5, 1.03 and 0.97 for example.
