How do I change color of input table itself and the font color?

I've seen the answers given on the question above in the forum.

Now, here's my question:

I have multiple tables in my form and I want to each give each table  a separate color. 

How do I this? What will the CSS coding for this be? 

I see that there are several Input tables added on your form. Could you provide us with more information on your requirement such as if you need the background color to be displayed for the form headers or the other cells, etc so that we can provide you with necessary assistance?

We will wait for your response. Thank you!
