chroma

I'm a little stuck... Click here to teach me more about this clue!

'quality of colour' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
I also know that both 'quality' and 'colour' relate to this answer.

'tea inspiring memory' is the wordplay.
'tea' becomes 'cha' (cha is a type of tea).
'inspiring' is an insertion indicator.
'memory' becomes 'ROM' (Read-Only Memory on a computer).
'cha' enclosing 'rom' is 'CHROMA'.

'for' is the link.

Can you help me to learn more?

(Another definition for chroma that I've seen is " hue".)
