I'm thinking of installing simple heatsinks on the SSDs in my desktop

they bring is well worth the price of UD$1.10 apiece in a pack of 5.

Here's an example: https://tinyurl.com/mpjar5bw There's a choice of
three colours on Amazon India - black, gold and plain aluminium. How
much of a difference, if any, will the colour make when fitted inside a
computer case? I expect that cooling will be mostly by convection than
by radiation.

Radiation cooling is tiny for low temp differences, so the finish
doesn't matter much.

Plastic packaged ICs usually have a tiny hot spot, visible on a
thermal imager. The real virtue of a heat sink is that it spreads the
heat laterally. A piece of flat aluminum woud work about as well.

The 1 mm "conductive adhesive" will dominate theta.
