If your G-Series keyboard supports multiple backlight colors, you can use Logitech Gaming Software (LGS) to set a backlight color for each M-Key either for all profiles or on a per-profile basis.

NOTE: Some keyboards support choosing between and blending two different colors. Others let you pick from a full-color selection. LGS detects which keyboard you have and lets you blend colors accordingly.

To configure the backlight color for an M-Key:

1. Open the Logitech Gaming Software:

   Start > All Programs > Logitech > Logitech Gaming Software

2. Click the light-bulb icon at the bottom of the LGS window.

   

   Depending on your keyboard, either the two-color (A) or full-color (B) color-picker palette displays.

   A                                                                                                   B

     

3. Select the M-Key you want to set by pressing it on the keyboard or clicking the highlighted key onscreen.

   

4. Click a color visible on the palette or, with the full color picker, use the RGB sliders to define your color.

   NOTE: The color onscreen may not exactly match the color on your keyboard. When fine-tuning colors, use the actual backlight on your keyboard for reference.

5. To change the color of another M-Key, click the M-Key icon in LGS, or press the M-Key on the keyboard, and repeat steps 3 and 4.

6. To set up per-profile backlight colors, select Enable per profile backlight settings at the bottom of the palette. Each profile will then display at the top for you to configure.
