Moral of the story is don't believe any colour on a computer monitor unless you have colour management and calibration over the whole process from start to finish. There's no way of knowing what lighting was used for the photos nor what white balance was used in the processing of the image ready for the web. After that there is no guarantee that the image carries the correct colour space tag nor that your browser will obey that tag even if it is correct. Then there is the calibration of your monitor and the colour balance of the ambient lighting where you are viewing it and that's before worrying about your own colour vision. Ultimately, there is no substitute for seeing a painted surface in the lighting conditions that you want it to look it's best, anything on the web is only a broad guide to colour.
