They brighten beds with pink among other colours (8,5)

I believe the answer is:

standard roses

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

'they brighten beds with pink among' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'other colours' is the wordplay.
'other' becomes 'standard' (I can't justify this - if you can you should give a lot more credence to this answer).
'colours' becomes 'roses' (rose is a kind of colour).
'standard'+'roses'='STANDARD ROSES'

Can you help me to learn more?

I've seen this clue in The Globe and Mail.
