How to conditionally colorize cells in Google Tables?

Question

Google Sheets

Hello. For some reason, I can’t color the cells in column A if, for example, there is a checkbox in B1 and it is activated.
What I did: I
used Conditions. formatting.

• Range: A:A
  
• Formula:if(AND(B1;1);;)
  
• Column A Cell Text Color: Red
  

Does not work.
And the 2nd option is to do it manually, i.e. "if b1 is true, then we do something with a1", but I don't know how to paint manually, Conditions can handle this. form, I think.
Tell me how to solve the problem?
Is there a manual for dummies, how to paint over a cell or something like that?
