Hey TI|BD, long time, no see. I've been experimenting with the CSE's color capabilities. When I went into the Catalog Help, I saw that TextColor('s argument was named [COLOR#]. This has lead me to discover several color codes, that you can use to replace with the CSE's color tokens.
19: LTGRAY highlight, YELLOW text
20: LTGRAY highlight, GRAY text
21: LTGRAY highlight, WHITE text
You might notice that some color codes are repeated, for example, BLUE is literally all numbers 1-10, and BLACK is both 12 and 24.
Edit: It appears that using TextColor(, 10 is the only one that works for BLUE. I haven't tested all the numbers, just 1 and 2, though. Also, 0 doesn't work as well.
