I want to use a color sensor for my arduinoArduino project with arduino unoArduino Uno to detect the colors red, green, blue, orange, yellow purple of leaves of paper and then light my rgbRGB led in those colors. I have no errors in my code, but it fails for some reason :( Can someone help me?

here is the code:

#define s0 8
#define s1 9 #define s2 10 #define s3 11 #define sensorOut 12

#define LED_RED 3
#define LED_GREEN 5 #define LED_BLUE 6

// Variabelen voor de kleurwaarden int red; int green; int blue;

const int RED_COLOR = (255, 0, 0); const int GREEN_COLOR = (0, 255, 0); const int BLUE_COLOR = (0, 0, 255); const int ORANGE_COLOR = (255, 165, 0); const int PINK_COLOR = (255, 105, 180); const int PURPLE_COLOR = (128, 0, 128); const int YELLOW_COLOR = (255, 255, 0);

int color = 0;

void setup() { // Zet de seriële communicatie op Serial.begin(9600);
