If you want to mimic a specific style you need a similar palette, nowadays you can cheat your way by just creating a pallette of X colors save it and use it in your engine or framework of choice. Using such a limited palette requires you to have excellent color knowledge and use advance pixel art techniques like dithering, anti-aliasing, etc. So if you want to mimic a oldschool art style you need to use a reduced palette, however 256 colors is still a lot if you know what people can do with just 16 colors. However, those old systems could not display all those colors at once, the SNES did 256 concurrent colors I believe. And then you still have the alpha with 32bit you can use to create transparency on your sprites. 8 bits account for 256 combinations and each channel can be combined with each other to create 256*256*256 = 16.777.216 colors. Usually 32 bit that includes an alpha channel that has 8 bits for each RGB value and another 8 bit for alpha transparency. You use a 32bit palette and you can use your favorite tool to draw something with that palette. Likely there is an extensive FAQ there about tools and how to become a good graphics artist. You may want to ask further questions about this subject in the "visual arts" sub-forum, which covers everything you'd want to know (and more) about making extremely nice pixel collections. To draw really nice sprites however, you need to practice a lot, it's a skill. Other production techniques are using 3D modelers, and rendering images from it.Īs for how to make them, the simple explanation is "open an image editor, and start drawing pixels until happy". There are also dedicated sprite editors, or animation editors. It starts with simple editors like paint, goes up to more professional editors like gimp or photoshop. Since a sprite is an image, you can make them with pretty much any image editor, since almost every image editor can produce RGBA images. Another popular format is RGB with 8 bit channels, but without the alpha, the opacity (which is the reverse of transparency). The technical term for 32bit graphics is RGBA, with 8 bit channels (red/green/blue/alpha are 4 channels, each 8 bit wide, so you end up with 32bit for each pixel). A video game displays dozens to tens of thousands of them, in all sorts of colours, shapes, and sizes. Sprites are just images, like PNG files, that you load and display at the screen.
