The textile industry sure thinks people perceive colors slightly differently. It's less of an issue now in textiles, since machines can check color using technology very similar to digital photography, but it wasn't in the past. The textile industry had (has?) people dedicated to checking colors, for example, to make sure that two batches of dye are "the same color". The majority of these jobs were (are?) held by women, since they apparently tend to have more repeatable judgements of color, and two women are more likely to "see the same colors" than two men. At least that's what we were taught back in the mid 1980s when I took a number of textiles classes in college. TTYL, DougF KG4LMZ
