I remember seeing a keyboard with transparent or crystal keycaps where pressing a key created colorful, watercolor-like patterns across the keys or keyboard. I can't remember the brand or model, and I'm still new to PC building. Was this a specific keyboard, or was it a standard keyboard fitted with clear keycaps and a custom RGB lighting effect?

A setup using clear or crystal keycaps on a Logitech-style RGB keyboard sounds very close to what you described. The watercolor effect would usually be a custom reactive RGB animation, not actual color being applied to the keycaps.
It may not be a special keyboard model. It was probably a regular RGB keyboard fitted with transparent crystal keycaps and a reactive lighting profile that spreads color when a key is pressed. Some optical keyboards can create effects like this, but the watercolor look is likely from the lighting software rather than the switches themselves.
Do keyboards like that come with transparent keys? Most of the ones I’ve seen are black, and I’m still choosing parts for my first PC.
Try searching for crystal keycaps combined with reactive RGB lighting or ripple RGB effects. The keycaps provide the transparent appearance, while compatible keyboard software creates the spreading colors when keys are pressed.

That might be the one. Do you know how I could recreate the watercolor effect?
