Booklet, brown and orange-yellow, about Clemenceau's end (8)
I believe the answer is:
brochure
'booklet' is the definition.
(synonyms)
'brown and orange-yellow about clemenceau's end' is the wordplay.
'brown' becomes 'br' (electronics abbreviation).
'and' means one lot of letters go next to another.
'orange yellow' becomes 'ochre' (ochre is a kind of orange yellow).
'about' means one lot of letters goes inside another.
'end' says to take the final letters.
The final letter of 'clemenceau' is 'u'.
'ochre' enclosing 'u' is 'ochure'.
'br'+'ochure'='BROCHURE'
(Other definitions for brochure that I've seen before include "Promotional booklet" , "Booklet or pamphlet containing information" , "Pamphlet, leaflet" , "Advertising pamphlet" , "Advertising booklet" .)
