im building a tron legacy disc upgrade and i want to be able to change colours so that i can go from a blue "regular" program to a green "virus" to a red "military" disc and preferably while the blade spin animation is going. how do i code it so that the animations look for a selected colour {thearter chase (colour)} instead of {theater chase 0,0,255} (forgive the improper syntax here, my actual code is writen correctly as seen in my post momentarily) i am also using a second board to control the c ring but that only uses a colour wipe and only needs to change colour so i know all i have to do is modify it along the lines of how i have to modify my disc code. i know how to add the second button, having seen a tutorial on that, what i havent figured out yet is how to make the first button pick the colour and the animations look to THAT for what colour to be
well here is my code for the disc in case anyone wants to build a disc anyway



#include <Adafruit_DotStar.h> //Comment out if using NeoPixels



// This is a demonstration on how to use an input device to trigger changes on your neo pixels.
// You should wire a momentary push button to connect from ground to a digital IO pin. When you
// press the button it will change to a new pixel animation. Note that you need to press the
// button once to start the first animation!

//#include <Adafruit_NeoPixel.h> //commnt out if using DotStar

#include <avr/power.h>
#endif


#define BUTTON_PIN 5 // Digital IO pin connected to the button. This will be
// driven with a pull-up resistor so the switch should
// pull the pin to ground momentarily. On a high -> low
// transition the button press logic will execute.

#define PIXEL_PIN 0 // Digital IO pin connected to the NeoPixels.

#define PIXEL_COUNT 45
#define NUMPIXELS 45
// set both of the above to the number of pixels in your strip
// Parameter 1 = number of pixels in strip, neopixel stick has 8
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_RGB Pixels are wired for RGB bitstream
// NEO_GRB Pixels are wired for GRB bitstream, correct for neopixel stick
// NEO_KHZ400 400 KHz bitstream (e.g. FLORA pixels)
// NEO_KHZ800 800 KHz bitstream (e.g. High Density LED strip), correct for neopixel stick
//Adafruit_NeoPixel strip = Adafruit_NeoPixel(PIXEL_COUNT, PIXEL_PIN, NEO_GRB + NEO_KHZ800);
// Here's how to control the LEDs from any two pins:
