What is color? In the computer perspective, color is the mixture of the three primary colors R🟥 G🟩 B🟦. Which stand for Red, Green and Blue respectively. By mixing these colors in different compositions, you can get any color between White ⬜ and Black ⬛.

Now, with the possibility of manipulating the color of a single square, imagine being able to manipulate the colors in many different squares all at once, that gives you an IMAGE!

Here is an example of what an image consists in terms of the RGB spectrum:

So basically, you have 3 sheets of RGB, and you mix them with their differing intensities 0 being the lowest and 255 being the highest to get a desired color in the output. (Output is gray here, but trust me, each square represents a color).

Y’all are prolly like, no way it’s this simple, but images are literally a bunch of squares T-T (see below for an example between high-res and low-res images)

The more the squares, the curvier it can get 😏(don’t quote me on that).

So essentially, the important takeaway here is that RGB or BGR is the standard way images are represented in almost any application today. These are more popularly known as color spaces. The RGB color space is used in common image encoding formats like JPEG, PNG, and BMP.

Well, if RGB is the standard color space then why do other color spaces exist? From a google search, it is apparently because different color spaces offer various advantages over other color spaces.

From my experience of image processing, I assumed that RGB is the GOAT and that I would be able to do anything with it, like color detection for example, in my case, I wanted to detect different colors in the image of a resistor.

But I was so WRONG, really wrong, after many failed attempts of trying to manipulate the RGB values in the image, I was at the brink of giving up. However, doing further research, I found out about the HSV color space. This was a color space designed to be able to filter out colors inside an image, no AI necessary.

So, to simplify it for you guys, the HSV color space is essentially the color wheel that we use every day.

With my sudden moment of enlightenment, I wanted to make my own script that lets me import any image of my choice and tweak the HSV VALUES TO CROP OUT COLORS MWAHAHA

Link to anyone who’s interested to learn more about HSV, there’s a cool simulation that you can check out!
