这些调色板有什么区别？How do the palettes differ?
Game Boy 只有 4 种绿色；CGA 是早期 PC 的 4 色模式（青/品红或绿/红/黄）；EGA 和 Teletext 是 16 色和 8 色的纯色；Commodore 64 和 ZX Spectrum 是 80 年代家用电脑的标志性配色；NES 是红白机的约 54 色；PICO-8 是现代“虚拟游戏机”的 16 色。每种都按原机器常用的 RGB 值近似，不同模拟器的数值可能略有差别。Game Boy has just four greens; CGA is the 4-colour mode of early PCs (cyan/magenta or green/red/yellow); EGA and Teletext are flat 16 and 8-colour sets; Commodore 64 and ZX Spectrum are the signature colours of 80s home computers; NES is the console's roughly 54 colours; PICO-8 is the 16-colour palette of a modern fantasy console. Each uses commonly quoted RGB values, which vary slightly between emulators.
抖动和像素大小怎么选？Which dithering and pixel size should I use?
Bayer 网点抖动会产生规则的交叉网纹，最有老游戏的味道；Floyd–Steinberg 更细腻，适合照片；不抖动则是干净的色块，适合图标和像素画。像素大小把每 N×N 个像素合成一个大像素，输出尺寸不变，2×–4× 就有明显的像素风，再大更像低分辨率屏幕。Bayer ordered dithering gives a regular cross-hatch pattern with the most authentic old-game feel; Floyd–Steinberg is finer and suits photos; no dithering gives clean flat areas for icons and pixel art. Pixel size merges each N×N block into one big pixel while keeping the output size — 2× to 4× already looks pixelated, larger looks like a low-resolution screen.
