Display the color combinations of color LEDs without using a Microcontroller

you Can Make a Simple Color Cycle Display For RGB (Red,Green,Blue) LEDs

Step 1: What You Need

You will Need:
1]1K potentiometer x3
2]330R resistor x3
3]LED Red,Green,Blue x3
4]Battery holder x1
5]Perforated boards PCB
6]Ribbon Wire

Soldering iron
Wire cutters/Strippers

Step 2: The Circuit Diagram

Here is a diagram showing the parts and how they are wired.  Solder the circuit

Step 3: All Done & Colour LEDs

Cool man. Students will really like this specially if you will enclosed it into a paper ball (origami) and then turn the lights off so they could make different lights. we could even instruct them to make cyan, magenta, yellow and other colors just by turning on and turning off some lights. they will appreciate the color theory.

But the LEDs each have their own max voltage... by using the same value resistor does this cause the blue to be dimmer when it is at "full brightness"?
