How to turn off rgb colour picker

[jonathanr31743583]

I have inadvertently turned on a RGB colour picker which comes on every time i use ctrl + alt + z to go backwards, does any one know what i have done and how to turn it off.

By using ctrl + alt + z it brings up a yellow box on any field on the screen with a colour picker and an RGB value.

Many thanks

That doesn't sound familiar at all, but you can try:

• Reset Tools To Their Default State 
• Delete The Photoshop Setting File

I had this problem but it's not about photoshop it was a program that i had previously installed called image magick and it was the reason everytime i press alt+ctrl+z whatever the programs that are opened even with the desktop it opens a color picker so i just uninstalled it and now i can step backward in photoshop without that annoying color picker
