HEX to RAL Converter

How the HEX to RAL converter works

RAL Classic is a fixed set of 214 standardized colors, so any HEX value almost never maps to an exact RAL code — there is only a nearest one. This tool converts your color into the perceptual CIE-Lab space and measures the Delta-E (ΔE) distance to every RAL Classic color, then ranks the closest matches. A smaller ΔE means a closer match between the digital color values; it does not guarantee a match to paint on a real surface.

From screen color to real paint

Screen HEX values are an approximation of how a RAL pigment looks under neutral light. For a critical match — facade, furniture, machinery — always confirm the suggested code against a physical RAL fan deck. To match a color you photographed rather than typed, use the photo-to-RAL tool or the RAL Picker app, which samples image pixels to suggest approximate matches; lighting and camera white balance affect the result.
