Here, I demonstrate how the colour panels work, demonstrate some of the colour tools and talk about using the right colour format.
In Photoshop there are many ways to use colour. It really comes down to what exactly you’re creating.
If you’re creating artwork for digital and web, you will want to use RGB colour and if you’re creating artwork for print you will need to use CMYK colours. You may want to use gradients, transparency or change your image into grayscale.
