There are only four words in the English Language that can not be rhymed with any other word.

What is interesting about them is that three of the four are colours,
silver,
orange
purple.

The other common word that does not have a rhyme is month.

Some other, less common words that have no rhymes are angst and scalp. There are also a whole raft of words ending in "-th", but some of these are number-places and thus are rather odd constructs, eighth, ninth and twelfth. There are also breadth, depth and width.

Unless of course. YOU know differently.

RANNNNNNDOM~! hehe

Depending on your accent, orange rhymes with doorhinge

Humm actually

silver = quicksilver-a heavy silvery toxic univalent and bivalent metallic element; the only metal that is liquid at ordinary temperatures

but purple and orange there is no perfect rhymes found but can still find ones that will rhyme

Orange = flange, estrange, arrange, cringe, challenge ect..

purple = apple, dimple,copple, ample, ripple ect......

I never thought of that , but your rite that wouldn't work here in Bahston, Wicked Pissa!!
