Colora review
A focused Windows utility for screen sampling, color conversion, and reusable palettes.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Colora is a free, open-source Windows desktop utility from Bluegrams for picking colors from the screen, converting values between common color formats, and creating reusable palettes. Its audience is designers, developers, and other Windows users who need a lightweight way to sample on-screen colors and organize them for later reference. The published feature set includes a zoomable screen picker, automatic history for recently picked colors, custom palette creation, saved palettes, GIMP export, and always-on-top and minimal-size modes. It is designed for Windows 7 or newer and is published under the BSD 3-Clause license.
Colora’s strongest area is direct screen sampling and color conversion. The zoomable picker supports more precise selection from visible content, while the conversion tools cover RGB, HEX, HSB, HSL, and CMYK representations. The history feature reduces the need to record each selection manually, and saved palettes provide a way to retain recurring color sets. Always-on-top and minimal-size modes also suit workflows where the utility needs to remain accessible beside another application. For users who work with GIMP, palette export adds a practical handoff from sampling to editing.
The product has a focused scope rather than a broad palette-generation workflow. Custom palette creation and saving are supported, but the feature set does not include image color extraction, accessibility checks, or a brand color library. Its integration coverage is also limited to GIMP, and the Windows-only platform narrows its fit for teams working across operating systems. Choose Colora when screen picking, format conversion, and saved palettes are the main requirements, particularly in a Windows-and-GIMP workflow. Choose another tool when you need image-based palette extraction, accessibility analysis, broader integrations, or more extensive palette-generation capabilities.
