[NTG-context] Contrast color in \setupinteraction

Hello, I use \setupcolors[state=start] \setupinteraction[state=start] and after I place the contents somewhere, the links that refer to the same page where the content is are red but others are green. I want them to be just the same. I found that \setupinteraction[state=start, color=middleblue, contrastcolor=middleblue] solves my problem, but is it the most elegant way to do? Can I just turn off the contrast? Best, Vyatcheslav Yatskovsky
