Anya Hurlbert is a Professor of Neuroscience at Newcastle University which she co-founded in 2004.  She has a background in physics, medicine and neuroscience and is a world-renowned expert in color perception and colour constancy. She is also interested in the intersection of perception and art. 

Does blue light wake you up or make you down?

Light not only enables people to see via the classical visual
pathway, but also affects alertness, mood, and biological
rhythms, via the non-visual pathway originating in the
melanopsin-containing retinal ganglion cells (mRGCs).
In other words, people both see and feel the colour of light.
The ability to tune light spectra in real-time with multi-channel
LED technology makes it possible – both in the lab, and, in
the near future, in the home and workplace – to optimise the
colour of light according to the desired task, time of day, and
environment, as well as in response to feedback from
wearable biosensors.

In this talk, I will discuss the results of experiments in which
we measured the effects varying spectra of light on visual
attention, mood, sleepiness, and melatonin production.
Although “blue” light indeed reduces melatonin production
in the evening, and reduces sleepiness, it also reduces
visual attention, and generally worsens mood.

Daylight and Colour Vision

The light that reaches us here on the surface of earth varies
rather drastically over time, in response to changes in
weather conditions, solar elevation and other factors.
Our visual system is remarkably successful in handling
this variability, so much so that we scarcely stop to think
about the difficulty of the task at hand.
In this talk I will talk about a dimensional perspective on
daylight and human colour perception, and consider
the possibility of a link between the two, focusing on
the work of Roger Shepard on the evolutionary
internalization of external factors.

Senior Research FellowNapier University

Malcolm is an artist by training and has extensive
experience of architectural lighting design and light art
from 24 years working on award winning international
projects.  He has his own professional lighting design
consultancy and wrote a book called "Lighting for Interior
Design" in 2012.

True Colours: explorations in art, design and research

Do you see colour the same way that I see colour?
As a person with and artistic training, it is possible that
I look at colour differently from a scientist.  But do
all artists or all scientists see the same, how do specialists
in each discipline see colour? Does a chemist see colour
differently from a physicist and do they see colour differently
from a neurologist?  How much does our training contribute
to our view of colour and do our professional silos prevent us
from seeing the world as others do? As someone whose
practice crosses art, design and strays into science, I am
always intrigued to know if the way we quantify colour helps
or hinders us. Do colour metrics reflect our real life
experience of light and colour? Are we actually measuring
the right things?


  1. Hi Josh, Great you are delighted with the 357. I have one myself since like 10 decades. I like it too, not modded as yours however.
    Right now it doesn't work, it chokes if warm. Brought to a neigbour of mine and he shall have a deeper look at it.
    It feels like some have had problem with the automatic decompression valve, so does yours have that?
    Have a fantastic day!How To Use A Chainsaw Sharpener

Colour & Lighting Event @ Newcastle University

A series of images from our event 'Colour & Lighting' held at Newcastle University. 

Colour & Interiors

Join us for our first official Event as Colour Collective UK! We have gathered some local talent to speak on the topic of colour in interiors at Northumbria University. Jo Feeley - Founder of Interiors & Lifestyle trend forecasting agency, Trend Bible (based in the Ouseburn) that provides trend consultancy and reports to a range of international lifestyle and homeware brands. Ruth Kilgour-Salmon - Founder of Litterarty Interiors, a local interior design firm that completes private and commercial projects across the country. Susi Bellamy - Fine artist turned luxury interiors designer, Susi has recently launched her homeware range at Maison et Objet in Paris. This event will be held in the ground floor lecture room in the Northumbria University School of Design. Please contact Louisa on +44 7749722256 if you have difficulty finding the location. We recommend parking at the Civic Centre and walking across the bridge for convenience. Free for members (annual membership £15) and for u…
