If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

I was all for RGB LEDs. Then I built a project using almost 100 RGB's. Go addressable and get there quickly. There may be a little learning curve but well worth it. Yes they are more expensive, but I have learned that almost every time I work on a project I wish I could scale the project.
Conclusion: Well worth it to get a few to tinker with initially or for specific needs, such as a single indicator light on a project.

The opaque coating gives much better colour blending than I expected — at least, better than a 50-pack of 5mm RGBs for the same price. It took some fudging around with different resistors, but I found a combination that gives excellent yellow, magenta, cyan and white.
Bit pricey, but totally worth it. I'm definitely planning on buying more of these. LOTS more. >:D
Helpful notes/observations: - Common cathode = connect the longest pin to ground, put resistors on other pins - For equal perceived brightness (and a really good white mix), I used: R-100Ω, G-220Ω, B-150Ω. (Off 3.3V from a Teensy/YwRobot supply). - At the same brightness, the red uses far more current (14 mA vs. 3.5 for green and blue, using the above resistors)
