Colors on the Macbook screen

[T0tal L0$$]

I accidentally pressed a shortcut so that the colors on my macbook is designed for visually impaired and can not find out how to get back. I have found out how to go from color to black and white.

Is there someone who remember the shortcut?

I think the shortcut is ctrl, alt, cmd, and 8 at the same time ... I am not sure though

You were absolutely right. It was just what was to
Thank you!
