Conditional Formatting Text with more then one value

Question

I am looking to have a row of 20 cells change font colour based on ABC to Z being white. Then 0 to 10 being blue. Then all the symbols being red.

Is there a way to do this? I found I can do this but I would have to make a rule for each character. I would like to have in one rule something like "a" or "b" and so on

Answer 1

for ABC...

=IF(REGEXEXTRACT(A1,"[A-Za-z]+")<>"",1)

---

for 123...

=IF(REGEXEXTRACT(TO_TEXT(A1),"\d+")<>"",1)
