This tool converts colors between Hex, RGB, CMYK, HSL, and CIELAB color spaces. It finds the nearest match in RAL Classic (213 colors), Federal Standard 595 (255 colors), and ANSI Z535.1 safety color standards using the CIEDE2000 perceptual color difference formula — the industry standard for color matching accuracy.
Whether you are specifying paint for structural steel, matching a powder coat color, verifying OSHA safety compliance, or cross-referencing international color standards, this tool gives you precise conversions with quantified accuracy (Delta-E).
Stop looking it up twice — run the numbers and keep the record.
