The Color Tools has a special color mixer you can access by selecting a color and choosing Edit from the drop-down or pressing
Ctrl + E. You can also open it by double-clicking on the system color you want to edit.
This tool allows you to have more granular control over change colors. There are two modes: RGB and HSV. RGB is the default mode and offers sliders for adjusting the red, green, and blue value of the currently selected color.
You can also use the input fields to the right of the slider to enter the exact value you are looking for. If the new color you select is the same as the currently selected color, you’ll see a warning icon in the color preview area.
In RGB mode, you can use your mouse to navigate the color space. RGB values are on the top and greyscale run along the bottom.
You can select a color by pressing the mouse down in the color space picker and dragging it around until you find one you like. This is a useful way to quickly find the general color you are looking for and then you can fine-tune it with the sliders and input fields.
If you switch over to HSV mode, you’ll notice that the color space and sliders change to reflect the new color mode.
In HSV mode, you’ll be able to adjust the hue, saturation, and value of the color you are editing. Everything else should work similarly to RGB mode.
The last thing to point out is the HEX input. You can use this to enter the exact hex color you are looking for.
When you are happy with the new color, simply hit OK and the currently selected color will be updated.
