Colors for markings, signs and panels
Note 1 – The specifications of surface colors given below apply only to freshly colored surfaces. Colors used for markings, signs and panels usually change with time and therefore require renewal.
Note 2 – Guidance on surface colors is contained in the CIE document entitled Recommendations for Surface Colors for Visual Signaling – Publication No. 39-2 (TC-106) 1983.
Note 3 – The specifications recommended in 3.4 below for trans-illuminated panels are interim in nature and are based on the CIE specifications for trans-illuminated signs. It is intended that these specifications will be reviewed and updated as and when CIE develops specifications for trans-illuminated panels.
3.1 The chromaticities and luminance factors of ordinary colors, colors of retro-reflective materials and colors of trans-illuminated (internally illuminated) signs and panels shall be determined under the following standard conditions:
a) angle of illumination: 45°;
b) direction of view: perpendicular to surface; and
c) illuminant: CIE standard illuminant D65.
3.2 The chromaticity and luminance factors of ordinary colors for markings and externally illuminated signs and panels shall be within the following boundaries when determined under standard conditions.
CIE Equations (see Figure A1-2):
a) Red
Purple boundary | y = 0.345 – 0.051x

Note – The small separation between surface red and surface orange is not sufficient to ensure the distinction of these colors when seen separately.
