The RGB backlight uses a tuple (a non editable data storage object) to store the intensity values of red, green and blue light. By mixing these values between 0 and 255 we can reproduce a great deal of the spectrum.
There’s no shortage of LCD displays for the Raspberry Pi, Arduino and other maker boards. We’ll start at the top end of the spectrum, with IPS displays. These are still LCDs, but they have rich and colourful panels that look great for media projects. The problem is that they’re more expensive, and quite fragile so should be kept away from heavy hands. They can also eat a large number of GPIO pins, so plan wisely.

In the middle we have single-colour OLED displays. These panels are vibrant, clear and more robust. They come in I2C, and SPI versions, so they don’t consume too many pins and they can be driven via a microcontroller. They are cheaper than IPS, but lack the wow factor of fast moving media with high colour content.
