These are lovely icons but I'm afraid you need to include at least two of the three primary colours in each icon. The first icon looks blue and orange rather than yellow or red so I can't currently include it in voting, and the third icon looks more red and black than red and blue so I can't include that one either. You are welcome to edit or replace any icon you like up until the deadline. Sorry to be a bit of a grinch, but I have to make it fair on everyone and that was the challenge description.
