brush tool

[*mark]

I'm looking through the help pages to solve this - I can see every setting, except the one that tells me why the paint brush tool doesn't respond. 

I'm on a new pixel layer,  unlocked and visible and still I cannot get the paint brush tool to paint. I have also tried it on existing layers and there's nothing happening (and it is definitely the PB tool I'm using). 

I'm moving from Photoshop and Affinity has a lot of great features but I really don't understand why using such a basic tool is made so difficult and convoluted. I've spent an hour looking for an solution.. 😐

Obviously there's a setting or mode I am missing... can anyone help me? and can I suggest basics like this are included on the same brush tool help pages? Thx

A few common issues:

• Having Protect Alpha enabled on the Context Toolbar.
• Having an active pixel selection, and trying to paint outside of it.
• Not actually using the Paint Brush Tool, but some other one.

Thanks Walt

Solved: Colour chooser showing white, but when I opened it up, somehow the picker sitting at the very edge of the chooser and painting nothing, moved it 1mm into the white zone and working perfectly ok - Tried to replicate it back to its original 'off' position but now responds with light grey and stays at the edge of the chooser... obviously a gremlin in there somewhere.

You're welcome. Glad you figured it out.
