Colourful band in front introduced by artist (7)

I believe the answer is:

rainbow

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

'colourful band' is the definition.
'rainbow' can be an answer for 'band' (thesaurus). I am not sure about the 'colourful' bit.

'in front introduced by artist' is the wordplay.
'front' becomes 'bow' (the bow is the front of a ship).
'introduced by' means one lot of letters go next to another.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'in'+'bow'='inbow'
'inbow' put after 'ra' is 'RAINBOW'.

Can you help me to learn more?

(Other definitions for rainbow that I've seen before include "weather feature" , "Iris was its goddess" , "Arc of colours" , "Coloured arch" , "Polychromatic arc" .)
