Arduino code help

Hey guys, So Im by no means good at coding. I can work with electronics, but the coding part of arduino is beyond me. I normally work with libraries that others have already created.  Im just wondering, is there anyway someone could help me write an arduino sketch for a personal project? Im using a arduino nano and a strip of 22 ws2812b led strips seen in my last instructable; https://www.instructables.com/id/DIY-Bike-LED-Lights/ I worked around the neopixal library until I got the rainbow cycle effect seen here (Not my video) https://www.youtube.com/watch?v=qUL7x_0r-bA Im just wondering if its possible to make the rainbow cycle code run between 3 different colors such as red green and yellow or red white and blue. here is my current code #include #ifdef __AVR__   #include #endif #define PIN 6 // Parameter 1 = number of pixels in strip // Parameter 2 = Arduino pin number (most are valid) // Parameter 3 = pixel type flags, add together as needed: //   NEO_KHZ800  800 KHz bitstream (most NeoPixel products w/WS2812 LEDs) //   NEO_KHZ400  400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers) //   NEO_GRB     Pixels are wired for GRB bitstream (most NeoPixel products) //   NEO_RGB     Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2) //   NEO_RGBW    Pixels are wired for RGBW bitstream (NeoPixel RGBW products) Adafruit_NeoPixel strip = Adafruit_NeoPixel(PUT THE NUMBER OF LED's HERE, PIN, NEO_GRB + NEO_KHZ800); // IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across // pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input // and minimize distance between Arduino and first pixel.  Avoid connecting // on a live circuit...if you must, connect GND first. void setup() {   strip.begin();   strip.show(); // Initialize all pixels to 'off'   // Some example procedures showing how to display to the pixels: } void loop() {   rainbowCycle(20); } // Slightly different, this makes the rainbow equally distributed throughout void rainbowCycle(uint8_t wait) {   uint16_t i, j;   for(j=0; j<256*5; j++) { // 5 cycles of all colors on wheel     for(i=0; i< strip.numPixels(); i++) {       strip.setPixelColor(i, Wheel(((i * 256 / strip.numPixels()) + j) & 255));     }     strip.show();     delay(wait);   } } // Input a value 0 to 255 to get a color value. // The colours are a transition r - g - b - back to r. uint32_t Wheel(byte WheelPos) {   WheelPos = 255 - WheelPos;   if(WheelPos < 85) {     return strip.Color(255 - WheelPos * 3, 0, WheelPos * 3);   }   if(WheelPos < 170) {     WheelPos -= 85;     return strip.Color(0, WheelPos * 3, 255 - WheelPos * 3);   }   WheelPos -= 170;   return strip.Color(WheelPos * 3, 255 - WheelPos * 3, 0); } Please let me know or if you can help ill take any advice Thanks!
