IMHO… blue doesn’t look too bad after removing the green off of the back of the panels but most other colors look a little washed out.
If your gauges are now green, once the coloring is removed you are left with a translucent white color, when either LEDs or paint is applied the color is washed out some. RED and White = Pink, Purple and white = light purple, etc.
I would buy new gauge faces in the color face & numerals you want and be done with it.
The final piece will look better and maybe more even in color too.
I tried the red, didn’t work for me so I purchased new gauge faces, now it looks the way I want.
