RAL 000 65 00

Neutral Grey

RAL 000 65 00 Neutral Grey is the quintessential mid-tone on the RAL Design grey axis at lightness 65 with zero chroma, sitting almost exactly between white and black in perceived brightness. It is a workhorse colour for industrial equipment housings, server rack panels, and utility enclosures. Its absolute neutrality makes it the ideal reference point when specifying lighter or darker greys in a coordinated palette.
