colors of toy LEDs

[mirthe24]

I got this LED from a toy I ruined.
I now want to change the pattern and colors of the lights, is that possible? And how would I do it?
I’m very new to this.

Appears these LEDs are in parallel.

Different colour LEDs have different Vf forward voltages.

Without a lot of cutting, modifications and soldering, you cannot change this as you suggested.

I gather these LEDs flash and/or fade to various different colours?

This is permanently built into each LED with that little black chip you see inside; it cannot be altered.
