This project demonstrates the relationship between different types of RGB color values. Play around with the sliders and see if you can figure out how the different values are related. If you want to make precise adjustments, click the slider knob once and then use the left/right arrow keys.
The major difference between my previous remix and this one is that I deleted the +/- buttons and added sliders for the R, G and B variables instead. Handling RGB color values in the decimal system is complicated. Just look at these examples: R:0 G:0 B:1 Decimal: 1 R:0 G:1 B:0 Decimal: 256 R:1 G:0 B:0 Decimal: 65536 Calculating the decimal value of a random RGB color without a calculator is quite challenging. But calculating the binary or hexadecimal value is actually quite easy. Let's do the above example with binary and hexadecimal (I have added spaces to make it more readable). R:0 G:0 B:1 Binary: 00000000 00000000 00000001 Hexadecimal: 00 00 01 R:0 G:1 B:0 Binary: 00000000 00000001 00000000 Hexadecimal: 00 01 00 R:1 G:0 B:0 Binary: 00000001 00000000 00000000 Hexadecimal: 01 00 00 At this point, I'm sure you can imagine what the binary and hexadecimal values for the following is. R:1 G:1 B:1 But the decimal value is a bit trickier to come up with, right? Here is the answer: Binary: 00000001 00000001 00000001 Hexadecimal: 01 01 01 Decimal: 65793 You can learn about binary and hexadecimal here: https://en.wikipedia.org/wiki/Binary_number https://en.wikipedia.org/wiki/Hexadecimal @njdavison has made several really great projects that are related to this topic.

Thanks to @njdavison and everyone else who keep teaching me all kinds of things :D
