I wonder why many of the on/off switches go from RED (orangey-red) to grey. Statistical facts: Approximately 8% of the male population are colour-blind. The most common type of colour-blindness is red-green. (Which means that red and/or green is seen as a grey.) Can something please be done about the toggle icons (and widgets). At home, in good lighting conditions, I can tell whether the toggle is on or off. But outside, in not so good lighting conditions, it can be extremely difficult, or at times, impossible, to tell if a toggle switch is on or off. At least, please try and make the differentiation between the two colours (on/off) have a far greater contrast. Thanks.
