The source light has an impact on how pigments appear. The colour temperature and spectrum of sunlight are both very warm. White light is often compared to sunlight. The uniformity of artificial light sources is lower. The light source must be specified in colour spaces that are used to represent colours numerically. Unless otherwise stated, lab colour measurements are taken under a D65 light source, also known as "Daylight 6500 K," which is similar to the colour temperature of sunlight. The Rosco R80 "Primary Blue" pigment is exposed to sunlight. The final spectrum, which gives the appearance of blue, is produced by combining the source spectrum and the Pigments Market reflectance spectrum. The additional components that are present with pigments can affect a color's saturation and lightness, among other characteristics. The colour can be influenced by binders and fillers.
