In Colombia, adobe is a building element, made of pressed cement. Obviously you give a light gray color, therefore an adobe color, it is that, light gray. It is a term used among masters of construction.
Surely it refers to a color profile created by Adobe® for its applications, and that thanks to the popularity of its document editors is already included in many cameras.
ADOBE COLOR This creation of a definition for a degree of brown is very unfortunate. The adobe is a clay brick that is cooked and can be manufactured with ANY type OF TiERRA. Therefore, its hue ranges from beige to dark brown or dark brown, depending on the country. Cooked darkens. It does not lighten the true color, unless there is an express agreement on the (color) PANTONE that we are talking about. Therefore, it can be any brown.
