We had pleasant blue kitchen walls so, when we built on a living room about 3 years later, the painter used the same paint code from the same supplier but it had changed to purple. The idiots admitted they had just dropped the old colour and re-used the code for the new paint.Er...without a photo I'm not sure anyone could help you with this one!
Thanks! I'd never really thought as to why Blue is not cited as a 'colour blind' instance. I know my father discovered he was colour-blind to Red when he tried to enrol as aircrew for his National Service.Colour is a very complex topic. We all see colours differently and the ambient light conditions can change the colour significantly. Also, the background light intensity can change a colour. The next problem is how the eye sees colour. With red and green these are electrical signals which go from the cones down the optic nerve to the brain. With blue, a chemical reaction occurs which then produces electrical signals which go from the cones to the brain. This is why blue colour blindness is so rare. The only way of comparing colours is to use spectral analysis which is what Audi use when mixing the paint and checking the final product. In the case of Hainan Blue this could consist of 8 or 9 different pigments some of which may not relate to the final colour.
I'm a tidy chap David! That wasn't long after I tiled the floor, £1100 of tiles, looking back I wish I'd bitten the bullet and used clay tiles instead.That garage is unacceptable John....far too tidy.
