Paletter
Paletter is a color schemer and palette manager for macOS designers and developers. It helps users create harmonious color schemes by applying primary color-harmony rules such as complementary, split complementary, triadic, tetradic, and analogous schemes. The app supports multiple color spaces including HSL, RGB, LRGB, LAB, and HCL, and includes tools for color mixing and contrast analysis. It is used by UI/UX designers, web designers, graphic designers, and developers who need to systematically generate and manage color palettes rather than relying on random color generation.

1 suggestionPaletter 4 has not been updated since version 4.3 (released in early 2022), and there is no confirmed native Apple Silicon build. The app continues to run under Rosetta 2 today, but with Apple removing Rosetta in macOS 28 (late 2027) — roughly 18 months away — you should begin planning an alternative now. Contact the developer (Toys Inc) directly to ask whether a native build is planned; if not, consider switching to a maintained color-palette tool such as Soulver (quick color calculations), Adobe Color CC (cloud-based palette creation and sharing), or Couleur (a free, actively developed native macOS app for color picking and palette management). If you have existing Paletter palettes, export them to a standard format (CSS, JSON, or Ase Adobe Swatch Exchange) before the deadline to preserve your color work.
