[Colouring in an addon] Need help

[Shyzhi]

So.. im trying to add some colours to my Aurora mod to match my UI more, but.. im not sure how to work out the numbers i need for the colours.

f:SetBackdropColor(0, 0, 0, a or alpha)

thats the line im editing, the numbers seem to be from 0 - 1 (Eg like 0.3) or somthing. im guessing how its how much red blue and green does into it but im not 100% how to work it out. Im trying to add the colour #121212 to it but im getting some issues can anyone help?

The 0's are the RGB values.

#121212 in hex, is 18, 18, 18 in RGB.

If you add a digit at the start, you should also be able to control it's alpha. Then again, I'm no addon coder.

The 0's are the RGB values.

#121212 in hex, is 18, 18, 18 in RGB.

would it be f:SetBackdropColor(18, 18, 18, a or alpha) or be f:SetBackdropColor(0.18, 0.18, 0.18, a or alpha)? :P im thinking its just 18.18.18 tho

Nope. Hex color values are in a #RRGGBB format - every color value goes from 00 (decimal 0) to ff(decimal 255).

You first need to convert the value to a decimal format (16 + 2 = 18), then divide it by 255 (the maximum for the hexadecimal color scale) to get the 0-1 scale value to use in SetBackdropColor.

In your example, the proper call would be

f:SetBackdropColor(18/255,18/255,18/255,a or alpha)

Or if you don't care about extremely-exact precision, you can simply use

f:SetBackdropColor(0.07,0.07,0.07,a or alpha)

Right, sorry. The digits are the RGB values in percentages.

RGB values go to 255. So 18 would be 7%, and written as 0.07 (assuming it accepts two decimals).

f:SetBackdropColor(0.07, 0.07, 0.07, a or alpha)

or

f:SetBackdropColor(0.1, 0.1, 0.1, a or alpha)

Thanks Treeston.
