|OCA Colour Chart orange square altered to neutral grey in 2 steps|
Obviously this task has shown that it is possibly to adjust colours to neutral and remove a slight colour cast. Hopefully any photograph taken would not have a cast as great that you would cause such an exaggerated shift as above. As demonstrated when you alter for the neutral all other colours will also shift.
The second part of this project entailed choosing an image which contained a colour that I thought should be neutral. I chose an image of a bus shelter taken near Brick Lane in London.

I then used Levels adjustment layers to increase the Blue channel. It took four very small increments to reach the correct Blue value of 166 and the saturation to read 1%. A fiddly task but worth it learning/understanding and refining to rescue any other image that otherwise might have been discarded.
