Excellent first idea. Could you remove the cascade of light from the circlular top element and make the blue of the two semi-circles a brighter shaed of blue. Then, make the bottom " IMI Healing Technologies" all one colur (either green or the brighter blue).
I do like #34 best, the solid colours together with the unique logo treatment. Can you please present this with the alternate colour pairing, which is purple and gold? We have some people internally who would like to see how that looks. Very good work to date!
I like the new elemnts introduced in #69. Because the MI in the logo is abstracetd my only request would be to make the name full underneath so that it reads IMI Healing Technolgies.
