That took me a moment and I almost went into Pertwee's era, but then I saw what's likely a dead giveaway (my learning that clicking on the image to see it larger really does help!

THE TWIN DILEMMA
Either Azmel's ship or the base on Titan III. That story was loaded with black, dull silver, and computer consoles that were wrapped in tinfoil and had big black "X"'s or "Z" adornments. That's got to be a background computer prop (nice screencap of it!). I also know of one other story from Colin's era that had likely repurposed some of those consoles, but I don't recall the keyboard lighting... It's a tough call but I'll go with that for now.
