My LED Fader Lamp Attempt

I am trying to make a simple fading LED lamp that fades-in and out multiple colors. I have 3 LEDs Red, Green and Blue in the same package. I turn them on simultaneously.

Trying to mix colors:

The combination colors were not very clearly visible. I haven’t made a diffuser yet. OK. I just placed a white envelope on it. The red being the most intense overwhelms the r+b, r+g and r+g+b with its color. Blue + Green looks sexy but I think I better diffusion would make it prettier.

Normalized Intensities:

Reduced intensity of Red.

I still would love to know

1. What is the best way (accurate method) to normalize the intensities and produce better colors
2. Better ideas to diffuse light

Cheers!
