Our Resource Library is for students, educators and researchers of all ages looking for information about light, colour, vision and how to see more. Visit the Resource Library now to see everything we have covered to date.

You will find that each page of the library deals with a different topic such as Features of Electromagnetic Waves and The Human Eye and RGB Colour. The pages are laid out as follows:

  1. Diagram: providing key information. All diagrams use the same graphic conventions to make them as memorable as possible.
  2. Dialogue box: for selecting download options for the diagrams.
  3. Questions and answers: a section where visitors can check out their general knowledge.
  4. Introduction: to diagrams with point-by-point explanations.
  5. Summary: of key terms used on the page.
  6. Additional information: How to use the resources on the page.

Diagrams can be downloaded in JPG and AI format.

The JPG format makes it easy to place or paste illustrations into essays and assignments. All diagrams are exactly the same width which means they will maintain a consistent size when used in essays. They appear at their best when allowed to run right across the page from margin to margin.

The AI format (Adobe Illustrator) allows diagrams to be edited.

Any text on the website can be cut and pasted into your own notes. Read our posts about Copyright and our Guide to Citations for more information.


If you are a new visitor to lightcolourvision.org and looking for information, you will find that one of the things that set us apart from the rest is the relationship between diagrams and explanations. Diagrams can introduce ideas in an instant but take several paragraphs to explain. They also help to communicate key facts that get buried in the details.

The diagrams shown below are in slide format. That means they are designed as if they were part of a presentation. The title is at the top and they have a dark background. We are now adding new versions formatted ready for use in articles and essays. These illustrations have no title and are on a white background.

If you can’t find the diagram you need then why not contact us. We may be able to help!

Kia ora to all our friends, supporters and visitors

It is now 2 months since we launched lightcolourvision.org and completed the crowdfunding campaign. Thank you for settling your pledges. We massively appreciate your support 🙂


As you can see,  the number of visitors is growing steadily with almost 8,000 unique visits in July. We are not yet tracking what happens once visitors arrive but two things are worth looking into:

  • Visitors who find what they need must be cutting and pasting or using Save Image As – there is no sign that our own download options are being used.
  • We are not receiving comments or feedback on the site. This is partly due to the plugin we were using being withdrawn. We are looking for a replacement!


  1. All the diagrams across the site have been updated to ensure they use a consistent design and to improve the information they contain. It’s been a major task with 124 images edited in total. Uploading the results is underway.
  2. The HOME PAGE has been updated. Feedback suggested that it was not immediately obvious what the site is about. Some of the terms in the menus have been altered and more explanatory information added below headings.


  1. Upload four more Articles. They are all complete drafts but need more exacting editing.
  2. Complete the written explanations for all RESOURCES pages.
  3. Instal a plugin to add Wikipedia entries to all the REFERENCES pages.
  4. Instal a plugin that allows us to add a DONATIONS option to the site with a secure payments gateway.


We are preparing a gift to send out to all our friends and supports. You can see one of them below. When it arrives, simply drag the file icon into a new browser window (except Internet Explorer) then visit the tab anytime you want to zone out as the pattern unfolds. (Don’t miss out, subscribe to the Newsletter under the MORE tab at the top of the page).


A quick look at lightcolourvision.org today suggests that the site is primarily concerned with light, colour and vision, not least with:

  • The physics of light and associated phenomena
  • The sensation, organization and application of colour in various contexts, not least digital tech
  • The mechanics of vision in terms of biological and neurological investigations

But the inclusion of the bi-line and ways of seeing more provides a clue to future plans. To understand where we hope to go with the site, it helps to have a sense of where we have come from.

The site has its origins in the research Jules and I were able to immerse ourselves in during our MA studies at AUT University, Auckland. The outcome for Jules was a body of photographic work entitled Touching a Sensibility: A Photographic Exploration of Haptic Experience and for me Living Events: A Metaphor for Design, a 110-page thesis.

Inevitably, the outcomes for both of us took the form of evidence rather than an explanation of our separate creative journeys, so there was no opportunity to link the work with the frames of reference others rely on to make sense of the world. In practice, it has taken the better part of a decade for the two of us to come to terms with the fact that both of our bodies of work represent different cartographic investigations of a single landscape and how they overlap.

The common ground emerged during a subsequent period of research when we had the opportunity to spend 5 months of 2017 at Tate Modern in the UK where we focused on the idea that, in any situation, there is always more to see and understand, but that the key question concerns the prerequisites to trigger such a process of seeing more.

Subsequently, our efforts have been focused, in immediate terms, on how to share a decade of research with Jules’ students, particularly her year 13 Scholarship students. The website meanwhile reaches out to a larger audience.

As it stands, the website contains resources that aim to convey a contemporary understanding of light, colour and vision. Seen together they convey how related fields of scientific investigation demonstrate a theory of seeing that underpins a common-sense understanding of how we perceive the world. A theory? Yes! It is a theory in the sense that none of what is known about light, colour and vision is actually evident as we all look around, see the world and locate ourselves within it. We just see stuff, whilst the mechanics of how is not directly evident.

Once we are confident that we have covered enough of the conceptual framework around light, colour and vision to be useful to site visitors, we will start to introduce another kind of content. The new material will introduce competing theories, not least ones that have emerged from our own research.
