gray color of #232 is too light. Is it gray applying on font? If so, my answer is yes. Honestly that is my problem so far. To applying light green on Do word, I worry there some odd relations between icon and text, its mean that the logo doesn't make sense anymore.
Make it all in blue, I still lean to make them as a part. Lastly when I tried to applying grey... i found there are no suitable grey can make them look better... :(( So confusing...
May be I better back to the first idea, make it all in just one color...
