Please make the lightbulb colours in the browser contrasting colours instead of similar colours.
I wear glasses and my eyes are not as young as they were, which means that the lighting in my room (which varies during the day, depending on the position of the sun) affects my ability to differentiate between a component or object that is visible from one that is not. Add to this the fact that all screens are not created equal and the colours you get on different screens can vary dramatically.
Which means that light grey and light yellow can be VERY similar colours.
As an example, make the visible object lightbulb a dark orange or some other HIGH contrast colour instead of light yellow.
Or, alternatively, add it as another option in preferences and allow your users to set these colours for themselves.
Regards,
Brett
