IMHO, the colour choice for the TV recording indicator (i.e. the red/orange circle shown in the guide, or in the recorded TV programmes list) is not the best. I understand that red represents a single (one-off) recording, whilst orange represents a series recording - and it is useful to have a clear distinction between these two modes of recording. However, the colours red and orange can be quite difficult to distinguish visually - especially if you have poor eye sight, colour blindness or even just a cheap TV set!
Is there some way to change these colours or, better still, define your own indicator icon to replace the red/orange circle?
