The currently used colour rendering index is based on an outdated colour space and chromatic adaptation formula. The perceived and calculated colour rendering of new light sources shows discrepancies. This becomes acute with the introduction of LED sources and increased use of coloured samples produced by ink-jet printers and colourphotocopy. Recent colour appearance models enable an advanced description of colour rendering. The present paper shows some visual experimental results and draws attention on possible updates of colour rendering calculation.
