四、 Viewing Color ⚫ Color perception is highly subjective and depends on ·the light illuminating the object ·the nature of the object itself ·the observer of the object 1. Light Source. Light has different wavelength compositions. Standardized viewing illuminations usually at temperature 0f 5,0000 Kelvin (K). Graphic arts light composition standardized at 5,0000K Visual color comparisons should be done underthese conditions. Temperature of 5,0000Kis similar to outdoorlighting at about noon. 2. Object influences color perception directly. Surface texture, gloss, geometry, and surrounding or adjacent promote optical illusions.四、 Viewing Color ⚫ Color perception is highly subjective and depends on ·the light illuminating the object ·the nature of the object itself ·the observer of the object 1.
