Thanks a lot for the detailed explanation!clair means clear/light in french, so beige clair just means light beige. it's more of just a descriptor since chanel often doesn't give official names to colors or bag styles. Official tags in france for seasonal light beiges likely say beige clair too.
Official color names are usually just "black" "navy" "brown," instead of specific shade names, which is why you'll see us use seasons so often like "21p brown" or "22c light beige." Calling the REV beige, beige clair instead of season + color helps us differentiate that we're talking about the classic beige instead of a seasonal light beige
