I have read that it rains, albeir sulphuric acid, on Venus and wondered whether rainbows could possibly be visable?

To human eyes, it is pitch-black on Venus, due to the effect of very deep clouds.
What little light reaches the ground is reflected many times, and comes from all directions. A good rainbow requires light from a single direction.
So even if there were a dispersive medium in the atmosphere of Venus, you wouldn't be able to see a rainbow.

To be fair, rainbows are relatively rare on Earth.
They need a "lucky" arrangement of the Sun, clouds and rain.
It's possible that such an arrangement might exist on Venus.

But I'd not waste much time looking for it.
