Notes on the colour of pollen
  • K. Lunau
  • Environmental Science
    Plant Systematics and Evolution
  • 2004
TLDR
It is shown that it is important to have information about the mode of the visual pollen display — crypsis or colour contrast against the corolla, pollen advertisement, or concealment — and the visual capabilities of the presumed pollinators in order to be able to discuss the signalling function of pollen colours.
How to colour a flower: on the optical principles of flower coloration
TLDR
This work uses an optical model to assess the contribution of different structures to the overall visual signal of flowers, and highlights that pigment localization crucially determines the efficiency of pigmentary filtering and thereby the chromatic contrast and saturation of the visual signal.
The colour of flowers in spectrally variable illumination and insect pollinator vision
  • A. Dyer
  • Mathematics
    Journal of Comparative Physiology A
  • 1998
TLDR
The results show that an illumination-dependent colour shift correlates to a decrease in the frequency of bees correctly choosing a colour to which it was trained, as well as a correlation to the rarity of some flower colours in nature.
FReD: The Floral Reflectance Database — A Web Portal for Analyses of Flower Colour
TLDR
The Floral Reflectance Database is a valuable new tool for researchers interested in the colours of flowers and their association with pollinator colour vision, containing raw spectral reflectance data for a large number of flower species.
Floral UV Features of Plant Species From a Neotropical Savanna
TLDR
The results evince that phylogenetic relatedness can constraint floral UV features’ diversification, but combinations of evolutionary and ecological processes may be expected in this scenario.
The colourful life of flowers
TLDR
The evolutionary and genetic mechanisms involved in flower colour shifts have been described in several taxa, providing insights into some of the processes that have shaped the diversity of flowering plants.
Detection of bright and dim colours by honeybees.
TLDR
Honeybees, Apis mellifera, were trained to detect coloured disks with either a strong or a weak intensity difference against the background, showing that target detection is independent of whether the colour is presented as a background or as a target in combination with the other colour.
Bright ultraviolet colouration in the Asian whistling-thrushes (Myiophonus spp.)
  • S. Andersson
  • Biology
    Proceedings of the Royal Society of London. Series B: Biological Sciences
  • 1996
TLDR
The first example of nearly pure UV colouration in passerines, the Asian whistling-thrushes (Myiophonus spp.), is presented and the barb-born UV-structure seems to be a modification of the taxonomically widespread ‘spongy structure’ producing blue and violet feather colours.
Responses of the blister beetle Hycleus apicicornis to visual stimuli
TLDR
Responses of adult Hycleus apicicornis to plant models of different colours, different combinations of two colours, or three hues of blue of different shapes are compared, suggesting that reflectance associated with colour could be a more important visual cue than shape for host location by H. apicICornis.

VEGETATION AND FLORAL COLORS REVEALED BY ULTRAVIOLET LIGHT: INTERPRETATIONAL DIFFICULTIES FOR FUNCTIONAL SIGNIFICANCE
TLDR
The importance of measuring floral colors as insects might see them is often ignored and many recent studies of UV reflections from plant parts (especially flowers) are unquantified and the discussions misleading, especially as they consider UV without reference to other primary colors for insects.
On the measurement and classification of colour in studies of animal colour patterns
TLDR
New methods make it practical to measure the colour spectrum of pattern elements (patches) of animals and their visual backgrounds for the conditions under which patch spectra reach the conspecific's, predator's or prey's eyes.
Insects as Flower Visitors and Pollinators
TLDR
This review concentrates on the entomologically relevant literature published since 1967 onination ecology, and has attempted to cover concepts, related disciplines, and insect taxa by reference to publica­ tions through which the reader may delve deeper.
Selection of exaggerated male traits by female aesthetic senses
TLDR
It is reported that mechanisms concerned with signal recognition possess inevitable biases in response that act as important agents of selection on signal form, and the existence of such biases may be sufficient to explain the evolution of exaggerated male secondary sexual traits, and elaborate signals in general.

The role of sensory adaptation in the retina.
  • S. Laughlin

    The Journal of experimental biology
  • 1989
Adaptation, a change in response to a sustained stimulus, is a widespread property of sensory systems, occurring at many stages, from the most peripheral energy-gathering structures to neural
S‐potentials from colour units in the retina of fish (Cyprinidae)
