Helix 9 color

Help. I’m missing something simple. I’m trying to change my depth colors. Example red/green. I have a 9 gen 2 with side image. I know it’s there. Right now I have a light brown and white.

Thanks in advance

Should be able to hit the menu button once and then scroll down to “sonar colors”. Do this while you are in the 2d view if you want 2d sonar color to change. DI and SI views if you want to change those colors.
