My colour picker is set to point sample, so it is not mixing colours, I am also on the correct layer. Does anyone know whats going on and how to fix it?
This may be a solution:
To fix this, when the eye dropper is selected, change the sample size at the top to Point Sample
If thats no fix, here is another ressource:
A lot of Photoshop problems can be fixed by dumping the preferences file: While launching Photoshop, Hold down Alt+Ctrl+shift on the PC or Cmd+Option+Shift on the mac. When asked to reset the preferences say yes. Before you do this, save your custom Patterns, actions, styles, brushes, gradients, shapes and color pallettes. These will also be reset. Tip: You can create an action to do this, so you have a one click backup! (Don't forget to save the backup action first)
