Same applies...

bubulindo:
Why don't you adjust the temperature to the PWM directly?

map(temp, green_low, green_high, 0, 255); //or some other PWM values that do what you want...

Ok, do this:

for (long temp=0; temp <100; temp++) {
  int blue = 255 - (map(temp, 31, 0, 0, 63) * 4);
  int green = 255 - (map(temp, 34, 26, 0, 100) * 2);
  int red = 255 - (map(temp, 50, 31, 0, 63) * 4);
Serial.print("blue ");
Serial.println(blue);
Serial.print("green ");
Serial.println(green);
Serial.print("red ");
Serial.println(red);

What do you see?
