don't define rgb primary color

When this is defined, selecting text in the code editor is invisible. Not sure why.

That is a weird one.

But looking at the community forum, https://community.home-assistant.io/t/changing-colour-of-template-editor-background/399359

Seems the same problem, and the solution is: "The two variables are:

• code-editor-background-color: # (main code page background)
• code-editor-gutter-color: # (line numbers column background) "

I will look into this one if this solves the problem...

Found the problem I think. rgb-primary-color needs to be something like 219, 185, 255, whereas right now it's being parsed as rgb(#dbb9ff) which doesn't seem to parse correctly

In the current version of HA, the background of the editor seems to be right.

However, you don't see what you select.

If I use the default theme (blue/orange), I see the following:

• I have selected the word temperature:
• The selected one is blue, the other strings are lighter blue.

In the inspector, this looks like this:

• the --rgb-primary-color is used with given transparency. This should work, however, if that CSS variable is wrong as stated by this PR, then the background color seems to do nothing!

• 

The value of the RGB primary color is:

And the original primary color:

So in this case, everything looks fine. Primary color is blue, and the background for selection is also blue.

Now I know what to check for the Material 3 themes...
