I like part of each concept and dislike part of each concept. So looking at both:
In design A (on the left) I like how "PEAK" is resolved. However, I do not like the condensed treatment of "DEVELOPMENT".
In design B (on the right) I don't care for the oversized 'peaked' letter A. It monopolizes the focus and keeps me from 'seeing' all of the elements as one entity, all at once so to say. But, I do like this design's treatment of "DEVELOPMENT" with the exception of removing the font's italic case using regular or book case.
So in summary, unite the top left 'PEAK' with an unitalicized bottom right 'DEVELOPMENT' to create your brand mark. Welcome to design C! This revision, will now present a palatable and pleasing difference in the cap heights of the two words. In design A, it feels like 'DEVELOPMENT' is trying to stretch upward to equal "PEAK", creating a distracting tension between the two words.
Color? I favor the coloring in design B, but not enough to require it.
I hope this helped. You have a nice start underway.
