QuoteHowever, none of my blue lights turn on, only the red ones.the only way to make any sense out of this whole thing is to take a single Led in hand, and play with it until you get the pin connections straightened out. Then, if I truly believed they had built-in Rs, I would take exactly one Led with theintent that I might be sacrificing it to the gods of thermodynamics, and apply full voltage to it, and see if it glowed for an instant and then forever flamed out.ONLY THEN would I hook up the original ckt shown. Better than blowing up $18 worth of Leds at square one.

Looking forward to the OP's schematic being posted on this one.
Oh boy... I'm not very good at schematics, but I'll try.
That's also how I know I've for sure got the wiring right for this particular model of LED. ......... and my question is why the blue lights aren't turning on when the red ones are on,
Um, I must respectfully disagree. I know which pin is the common anode, and which ones are the ground for each respective color. What other information should I know about this? The lights work fine on separately, and when all are set to one specific color, and I can flash one between blue and red and green no problem in quick succession. Is there something I am missing here? Because I don't see how this is relevant when we established much earlier in the thread that my issue is probably due to a lack of current control or lack of forward voltage bias separation between the LED's that I have. Sorry if I'm coming across as rude, I'm just genuinely confused.
I'm just genuinely confused.
Any particular recommendations for a software package to do that with?
thank you for the recommendation for the three grounds and resistor on Adafruit.
