Hi,

I created my own test field to test the colors.

I paste this value into CSS using:

{theme='test_color'}

Question: How do I change the value from HEX to RGB? I would like to put this value in a variable as it is done in the default IPS theme (:root)

Instead:

:root {
	--test-var-color: {theme='test_color'};
}

Effect:
:root {
	--test-var-color: #2193e6;
}

I want it to look like this:

:root {
	--test-var-color: {theme='test_color'};
}

Effect:
:root {
	--test-var-color: 33, 147, 230;
}

Is there a ready way for this? Do I need to change this value using a function in php?
If there is a ready solution, I suggest adding this to the documentation.

Any theme settings that are "color" fields will automatically be turned into CSS variables for you. If your theme setting has the key "test_color" (like in your screenshot), the CSS variable will be named --theme-test_color. No need to create the CSS variables yourself 🙂 

Great message! It will save me writing additional code. Thanks!

To expand upon your original question, if you needed to manually convert hex color code to rgb, there's a template plugin (which works in CSS files) for that.

{hextorgb="$variable" opacity="1"}

{hextorgb="#fff" opacity="0.1"}
