Also, I should mention that have no idea how this works on PC, if the sliders have set tick marks or if you can move them freely, so the second number is the actual RGB value in case you need it. Should also add that I am on Xbox One, but I can't imagine the PS4 version would use a different amount of tick marks on the sliders for no reason. So if you start from the bottom, the first time you move the slider, you'll count '1.' Understand? Good.
All the way down is 0, all the way up is 20. I'll give each R, G, and B slider name a number that corresponds to the number of ticks you move the slider.
For anyone who wants to use any of the three four old colors from 3 and New Vegas for their HUD, I've created a list of slider settings.
