Conditional formatting in a formula

Hello,

I'm working on a file now where I have compare competitors.

Let say I have this information


A B C
1 name 1 10 20
2 name 2 20 10
3 name 3 10 20

Now I would like to hightlight cell a1 blue if cell b1 is the highest and red if c1 is the highest.

Is this even possible>

Please help!
