Just to expand - if you're referring to using Glyphs, red means that the roll was lower than what your current glyph has applied. IE, for example if you are using a 5-star speed glyph and your item has currently got +3 on speed from a previous glyph, a red bar indicates that the roll was 3 or lower.
