Desperate Grammatical Question - Which makes more sense?

I got into an argument on a forum, where my text posting color (magenta) was too close to another user's text posting color (red). I expressed the sentiment that I don't like my color to be too close to someone else's by saying, "I don't like [our colors] to be too close to be distinguishable." The other user corrected me, saying, "Don't you mean, 'I don't like [our colors] to be too close to be indistinguishable'?" I argued that, no, my version was correct, because to be "too close to be distinguishable", with (from one another) following understood, makes sense, whereas "too close to be INdistinguishable" doesn't, in my context. Right?
