The feature of setting sql background color per db connection is on high demand on toad forums. Can you update if it is in the future dev plans?
You can set color for your database connection in Toad for Oracle login window.

Do you need something more?
I made a mistake, I thought you talk about photoshop image color correction, but you ask about sql background color. But ti you ask about image then I will recommend you for phototrims.com/color-correction-service.php this web. But I’m sorry that I can’t help you in this case.
