Custom Color Master

Pick, convert, copy colors

Only for Mac

Mac

Now with a built-in converter: paste any color value and turn it into any of 19 formats. Your clipboard is checked automatically when you open the window. Custom Color Master is a lightweight menu bar utility that lets you pick any color from your screen and instantly copy its value in the format you need. Click the eyedropper icon in the menu bar, choose a pixel anywhere on your screen, and the color is captured to your history. Each entry in the history has its own format dropdown - switch between formats independently for any picked color, and copy the value with a single click. You can also paste a color value in any supported format and convert it — the result lands in your history alongside your picked colors, ready to copy. Supported color formats include HEX, RGB, RGBA, HSL, HSBA, HWB, OKLCH, CMYK, SwiftUI, UIColor, and several other developer-friendly representations. All data stays on your device - no accounts, no tracking, no network connection required.

Color converter You can now paste a color value into the input field at the top of the window, choose a target format, and convert it — no need to pick from the screen first. Every format the app displays, it can also read: HEX, hex integers, RGB, RGBA, RGB floats, HSL, HSBA, HWB, OKLCH, CMYK, SwiftUI and UIColor initializers, and more. Converted entries are marked with a small badge so you can tell them apart from colors picked off the screen. Clipboard detection When you open the window, the app checks your clipboard. If it holds a recognizable color value, it's filled into the input field automatically. Anything else is ignored, so ordinary copied text never ends up there. Improvements - Format dropdowns are wider — full format names are now visible instead of being cut off - Newly added colors briefly highlight in the list so they're easy to spot - The window now opens on the desktop you're currently using, and puts itself away when you switch to another one - Keyboard shortcuts in the input field now work correctly with non-Latin keyboard layouts
