I'm trying to blend RGB to make other colors, so I was under the (wrong) impression that all the colors can be turned on at the same time with each one being able to dim independently. I tried connecting a power source with all three colors in parallel. It seems like R G B is prioritized, so only one color can be on at a time. Any way to turn all colors on at once? Looks like a standard emitter with R+, G+, B+, and -. I bought 10 for $16 from china.
You haven't told us what the LED is. You haven't told us how you connected it. You haven't told us how you're trying to control it.
The best answer I can gave based on what you said is: "Fish".
