Along the top of your screen you’ll see the options bar, this changes depending on which tool is selected from the tool box. It allows you to change brush size, text size, colour and so on.
Along the left hand side of your screen is the tool box. This is where you’ll find all your tools; the paint brush, eraser, pen tool, text tool, crop tool and so on. Right at the bottom of your tool box, you can select foreground colour – this is the colour of your paint brush, text, shape and anything you draw. The background colour is the colour of the background layer, the colour of the eraser tool and the end colour of a gradient (gradients go from foreground to background colour).
