Biological Optics: Seeing Colours in the Dark

The intensity threshold of colour vision has been behaviourally tested in birds; the results show that parrots lose colour vision in brighter light than humans.

Colour Appearance Modelling for Self-luminous Colours

An experimental setup and procedure for the evaluation of selfluminous colours viewed against both dark and luminous backgrounds is presented. Physical and visual data of self-luminous colours is gathered in order to develop a Colour Appearance Model for self-luminous colours under different viewing conditions. This model is needed for the evaluation of light sources.

Interactions between colour and synaesthetic colour: An effect of simultaneous colour contrast on synaesthetic colours

We investigated whether simultaneous colour contrast affects the synaesthetic colour experience and normal colour percept in a similar manner. We simultaneously presented a target stimulus (i.e. grapheme) and a reference stimulus (i.e. hash). Either the grapheme or the hash was presented on a saturated background of the same or opposite colour category as the synaesthetic colour and the other s...

I watched guests getting up on their feet to dance with the newlywed couple. Bless them.
