Here is a collection of colour palettes for pixel art that can be used, as well as some useful resources. Feel free to download the palettes. I will update this periodically as I discover more cool colour palette related resources.
The palettes are set up to be imported into a program like Pyxel Edit, which is currently my Pixel Art software of choice. They’ll line up as shown if you put the width and height I have provided in to Pyxel Edit’s colour palette tools.
How To Practice Pixel Art
Generally, as a beginner, working with less colours is better to practice and learn how to use colours properly. I would recommend practising with Gameboy, and then maybe following it up with Pico8, Micro 12 or AAP 16.
The video below is a great example of how to get started:
Auto-Generate Your Own Custom Palette
There’s a fantastic website that lets you auto-generate your own colour ramps for free.
Here’s a really good tutorial that teaches you the basics to get started making your own custom colour palettes. Starting out, I liked to use the auto-generator above mixed with the techniques in this tutorial.
You can right click and save any of the palettes as an image. You can import them into software like Pyxel Edit and it will set up the colour palette for you as the only colours you can choose from.
For Pyxel Edit you won’t need to resize the images, but if for some other reason you do need to resize them:
Shrink the images down to a 1 pixel scale – set the pixel width and height to be the width and height given in this post (if you’re using Photoshop, use Nearest Neighbour as your resize settings)
Enlarge the palette, ideally in multiples of 100%, to the size that you want
