Color different squares in a grid

[Enzee]

Hello,

 

Sorry for the newbie question, but here it goes.

 

My goal is to set a grid in my document and then make that grid allow me to click each and any of the squares to change color of that particular square. I understand that I can line individually created square boxes up and then color them differently and individually, but can I do this with a grid in some way?

 

I have both Photo in the iPad and Mac Desktop version so if I can do that in one version or the other, that is fine.

 

Thanks in advance for such a simple question. Much appreciated!

Welcome to the Serif Affinity Forums, @Enzee.

Draw a grid with the Pen Tool, add a new Pixel layer on top, and choose the Flood Fill Tool. If you set the Source to ‘Current Layer & Below’ the lines of the grid will constrain the flood fill to lie within the grid cell where you tap (or click on the desktop version).
