Is your feature request related to a problem? Please describe.
The color of a glow is referred to as "custom color" everywhere else than when selecting the color in custom conditions. To enable the use of glow color you have to set use custom color = true.
Would perhaps be less confusing to call it the same thing across the board.
Describe the solution you'd like
Rename Glow - Color to Glow - Custom Color

Describe alternatives you've considered
Rename every instance of "custom color" to "color" 💃
