Lospec offers various tools and tutorials for creating "digitally restrictive art", typically pixel art that restricts the pallette and resolution in honor (or explicit imitation) of retro computer hardware.
The biggest collection of pixel art tutorials on the net! Search by topic, author or medium to find the perfect article, video, image or book for you.
A searchable collection of palettes for pixel art. Every palette can be downloaded in 6 different formats, and imported into nearly any software used to create pixel art.
The Lospec Pixel Editor is a free, easy to use tool for creating pixel art that you can use right in your browser.
It's the work of Sam Keddy, who operates a patreon that you can pledge to to help further develop the site.
