Terms of Use

Last updated August 26, 2026

Short and in plain language, since this is a personal site and not a service you are buying.

What this site is

A collection of personal writing by Wren Callahan about colour, light and the difference between the two. It is offered as it is, for reading.

Not professional advice

Nothing here is professional advice, and nothing here is a recommendation tailored to your particular room, light or house. These are notes from one north facing flat. Anything you try, you try on your own judgement, on your own walls, and at your own risk. Paint fumes want ventilation, old paintwork can contain lead and should be tested rather than sanded on a hunch, and anything structural or electrical belongs with a qualified trade.

Accuracy

I write carefully and I still get things wrong. Everything here is accurate to the best of my understanding at the moment it was written, and some of it will age. Pages carry their last updated date so you can see how old a piece of thinking is. If you spot an error, write to hello@lifeinsoftcolors.org.

Colour on your screen

Every screen renders colour differently, which is the subject of several articles here. Nothing shown on this site should be treated as an accurate reproduction of a real colour, and no colour decision should be made from a screen alone. Test it on the actual wall, in the actual light.

Copyright

The writing on this site is mine. Quote a paragraph with a link back and no permission is needed. Reproducing a whole piece, or using anything here to train a model or to fill another site, needs asking first. Photographs are licensed from their photographers and are not mine to pass on.

Links out

Links to other sites are there because they were useful at the time. I do not control what happens on them, and a link is not an endorsement of everything on the other end. Some of them are affiliate links, described in the affiliate disclosure.

Liability

To the extent the law allows, I am not liable for any loss or damage arising from something you read here or from something you did after reading it. The site is provided without warranty of any kind, including that it will always be available or always be free of errors.

Governing law

This site is published from the United States, and these terms are read under the law of the United States.

Changes

These terms can change. The last updated date at the top of this page is the honest record of when they last did.
