For example, as part of my ear training I sing an A or handful of other notes before I've touched my guitar or had a chance to compare it to something else. 99% of the time I get it right, and this is sort of getting into absolute pitch territory, but real establishment of the perception of tones should mean that they're as clear in your mind as imagining different colors.
When I said I can't sing, I meant I can't even sing the right notes when I try. I have almost no control over my voice when I sing. I know when I'm singing a little too low, but I try to change that and then it's too high. There's a small part that's a little less than an octave that I can sing the right notes.
