The light blue/dark blue combo really isn't anything that groundbreaking in logo design. Paired with black, white, or gray, still very common.
Anyone care to guess what colors are in the Trixie logo? Light blue and dark blue. That doesn't mean anybody is buying them. If there was a large med device conglomerate with ANY colored logo who had entered into a co-development agreement which also spots them tens of millions dollars, I'd be thinking acquisition was in their future.
In terms of calculating odds that logo colors would match, one needs to determine which color scale to use; e.g. ROY G BIV (with black and white gives only 9 options) vs Pantone and its 1867 different colors, or any of dozens of other possible scale selections. Then we must determine tolerance of the match (how close is close enough to call it a match).
Also, let's look back at Titan's prior logo. Any guesses? If you guessed other than light blue and dark blue, you're wrong. A little darker than the current combo, but blue represents calmness and trustworthiness, so it remains a very popular choice in logo design.
Logo colors are a very minor coincidence and certainly no basis for a multi-billion dollar business transaction. And I expect that once this deal concludes, Titan and its logo are likely to go away completely because they will not have had any substantial prior sales to support like Mazor and Covidien. And it would be a better business move to absorb Titan into another existing MDT-owned brand for all their surgical robotics; Hugo won't be a Titan product, and there would be additional confusion with the MDT-owned Titan Spine (which did not have a blue logo!).
