Doing a Roulette worksheet, huh? <g>
I think Conditional Formatting would be the best to use. Select your
"particular cell" (I'll assume you selected A1 for this example...change the
A1 in the formulas below to whatever the address is for the actual
"particular cell" you selected) and then click Format/Conditional Formatting
from the menu bar. On the dialog box that comes up, select "Formula Is" from
the first drop down and then put this formula in the empty field to its
right...
=AND(MOD(A1,2)=1,A1<>"")
Then click the Format button, select the Patterns tab and pick the red color
you want. If you pick a dark red color, then you might want to click the
Font tab and make the Font color white for readability. When done, click OK
to go back to the first dialog box. Next, click the Add button and select
"Formula Is" for Condition 2 (the condition you just Add'ed) and put this
formula in the empty field to its right...
=AND(OR(A1="0",A1="00"),A1<>"")
