You don't need to say "in color"

You don’t need to add “in color” after an adjective for color.

For example, the phrase “in color” is unnecessary in these sentences:

Red blood cells are red only because they contain a protein chemical called hemoglobin which is bright red in color. (Source)

Yellow Lustrium® - Same characteristics as Lustrium®, but yellow in color because of coating with 23 karat yellow gold. (Source)

Of course, names of colors are sometimes used figuratively; for example, “feeling blue” (depressed) and “a green product” (environmentally friendly). In these cases, some explanation may be needed.

The Takeaway: Don’t automatically add “in color” after an adjective for color. Do it only if the meaning would be unclear without it.

See disclaimer.
