I really like #21. The colors are bright, the logo is crisp. I like the use of the pause symbol. The font is good. I like use of both blue and green in symbol & words.
Entry #19 is good. The symbol is unique. I like that both blue and green are used in the symbol & words. I like the font - simple and clean. The symbol is like a flower, but also could be a seated figure with arms up and open. Two green vertical rectangles are similar to the pause symbol.
I still prefer the font in #19 instead of the new font in #165, #166, #167. Can you please try #19 again but this time switch the colors in the symbol so that there is blue in the center and green on the outside? Leave the font the same.
Can you put all three center parts in blue and only the outer two pieces in green? Also try a softer font and give me an option with italics. Please keep the 'P' & 'Y' in upper case with all other letters in lower case.
