Spencer, the negative number means the input color is out of gamut, i.e., there is no single color in sRGB color space that could match AdobeRGB (255, 0, 0). If what you want is to obtain some close color, littlecms (not transicc but the library) has ways to do that. transicc always works in unbounded mode, that is, marks impossible colors as negative or above 255.
