Columns H through K contain codes: reg, f, s, b, h, j

All of these codes fall into one of a few colors:
reg, h = red
s, b, j = blue
f = pink

Is is possible to write one conditional formatting rule to turn the cells containing "s", "b","j" blue (or all the 'reg', 'h' cells red) or do I need a rule for each string? I CANNOT get an OR() formula to do the job, but I feel like it should work.

Thanks.
