Whir of Invention won't allow you to tap Kilo, Apogee Mind for Blue despite being a W/U/R card.
I was attempting to cast Whir of Invention where X = 3. I tapped 3 lands for mana, an Arcane Signet for 1 blue mana, and a Simulacrum Synthesizer for Blue using the Improvise alternative casting cost on Whir. This would leave the remaining cost at one blue mana which could be paid by tapping Kilo. The problem is that when I attempt to tap Kilo for Improvise the client won't allow me to tap it. If I pressed Z to undo tapping Simulacrum I could tap Kilo for the Improvise cost, but the client would only add white mana.

Improvise only lets you tap artifacts to pay for the generic part of the cost. It is different from convoke. You cannot pay the colored portion of an improvised spell by tapping artifacts.
