Receiving honour, having a bouquet devoid of colour (10)

I believe the answer is:

achromatic

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

'devoid of colour' is the definition.
'achromatic' can be an answer for 'colour' (achromatic colour is a kind of colour). I am not certain of the 'devoid of' bit.

'receiving honour having a bouquet' is the wordplay.
'receiving' indicates putting letters inside.
'honour' becomes 'ch'.
'having a bouquet' becomes 'aromatic' (I can't justify this - if you can you should give a lot more credence to this answer).
'ch' going inside 'aromatic' is 'ACHROMATIC'.

Can you help me to learn more?

(Another definition for achromatic that I've seen is " Without colour".)

I've seen this clue in The Times.
