What colour derives from the Latin root word meaning shade?

Answer 1

Umbra

Answer 2

The Latin word for shade or a shadow is umbra, which is the origin of the English word "umbrella", a small shade you carry around with you.

Your question implies that you believe the word umber (a paint colour) is derived from Latin umbra, which is a false deduction, despite their similarity. In fact the term umber (a brown pigment consisting of manganese oxide) comes from the Italian term terra d'ombra, meaning earth from Umbria - one of the regions of Italy where such pigment was found. The name of the region derives from the Umbri tribe who lived there in ancient times.

The use of the term "umber" for a paint colour was not used in English before 1650, in other words during the modern era, when it is much more likely to have come from the name of the Italian region than from classical Latin.
