The addition of the name 'Varychrome' to ERCO luminaires identifies those luminairs whose colour can be changed dynamically.
These luminaires are electronically controlled to generate variable light colours by additive colour mixing of the primary colours red, green and blue (RGB technology).
They enable an infinitely variable adjustment of different light colours.
The advantages of colour mixing using coloured lamps are that complex mechanical components are not needed and colour filters with low transmission are avoided.
The term 'Varychrome' refers to the mixing of colours.
It is derived from the Latin adjective 'varius' meaning different and the Greek word 'chroma' for colour.
