Cang

Its meaning shifts with the word around it.

Early forms of 蒼 appear on bronze inscriptions and in manuscripts from the ancient state of Chu during the Warring States period, before later standard scripts. The Shuowen, an early Chinese character dictionary, explains 蒼 as the color of grass: 艹 is the grass component, and 倉 hints at the sound.

That color sense can shade toward dark blue-green. 苍白 means pallor, while 苍老 describes an aged or weathered look. Translate the compound, not just 苍.

What does 苍 mean when someone sends it?

Read the compound first.

苍天 and 上苍 refer to heaven in elevated wording; 苍生 means people as a whole; 苍白 describes pallor. These established compounds do not all label the same color.

If someone sends 苍 alone, the message does not settle one precise meaning. The surrounding word or sentence decides whether it evokes color, heaven, people, pallor, or age.

Is 苍 the same as 蒼?

Yes; 蒼 is the traditional form of 苍.

In simplified Chinese, 苍 corresponds to traditional 蒼. The grass component stays the same, while the lower component is written 仓 in 苍 and 倉 in 蒼. Text usually follows one script convention.
