How bees discriminate a pattern of two colours from its mirror image. by Adrian Horridge

“…A century ago, in his study of colour vision in the honeybee (Apis mellifera), Karl von Frisch showed that bees distinguish between a disc that is half yellow, half blue, and a mirror image of the same. …”

Bat eyes have ultraviolet-sensitive cone photoreceptors. by Brigitte Müller, Martin Glösmann, Leo Peichl, Gabriel C Knop, Cornelia Hagemann, Josef Ammermüller

“…Mammalian retinae have rod photoreceptors for night vision and cone photoreceptors for daylight and colour vision. For colour discrimination, most mammals possess two cone populations with two visual pigments (opsins) that have absorption maxima at short wavelengths (blue or ultraviolet light) and long wavelengths (green or red light). …”

A numerical study of red-green colour opponent properties in the primate retina. by Momiji, H, Hankins, M, Bharath, A, Kennard, C

“…A persistent debate in retinal colour vision is whether the centre and the surround of a ganglion cell receptive field receive dominant inputs either from L or M cones in an antagonistic manner (the selective wiring model) or mixed inputs (the mixed wiring model). …”

Impacts of the retinal environment and photoreceptor type on functional regeneration by Michèle G DuVal, W Ted Allison

“…Cones are key: For patients suffering vision loss, cone photoreceptors are a required cellular component to restoring daytime vision, colour vision, and high acuity vision. The challenges of regenerating cones contrast with logistic challenges of regenerating rod photoreceptors, which underlines the importance of evaluating context in degeneration and regeneration studies. …”

Colour blindness-A rural prevalence survey by Natu Maya

“…Colour vision is important for aeroplane pilots, motor drivers, seamen and signal men for their professional work Not much of attention has been paid to population studies of colour blindness as there is no interference with daily routine in majority of persons However there is a need to undertake community wide prevalence surveys which could be useful in study of other genetically transmitted diseases…”

Hue. by Cheah, Joanna Siew Ling.

“…It begins with a research on understanding colour blindness, the methods of identifying colour blindness, the problems and challenges faced by people with Colour Vision Deficiency (CVD). Through this, hue seeks to provide possible solutions to aid a colour-blind person so as to promote a more colour-blind friendly environment.…”

The misuse of colour in science communication by Fabio Crameri, Grace E. Shephard, Philip J. Heron

“…The accurate representation of data is essential in science communication, however, colour maps that visually distort data through uneven colour gradients or are unreadable to those with colour vision deficiency remain prevalent. Here, the authors present a simple guide for the scientific use of colour and highlight ways for the scientific community to identify and prevent the misuse of colour in science.…”
