Okay, thanks for the variants, and I'm really liking where this is going. However, after looking at everything, here is what I would like to see:
- Start with #15
- Slightly compress horizontally (make it narrower) "OnLine" - I would estimate shorten the entire word about 1/2 of the width of the "e". Do not change font height, only change width.
- Use tagline "LEARN. RETAIN. PERFORM." (w/o quotes), but stretch font full width of logo (do not change font height or vary kerning, only overall width to match logo width)
- Darken grayscale items (I would estimate using #444444 for font color and darkest part of sphere color, but use your judgement)
