Colors can be darker or lighter: and this in color terms is called Luminosity. Color can also be saturated (vibrant) or desaturated (neutralized). Desaturation can be done to a lesser extent or more, and when it happens to the maximum extent possible, that’s the same as completely neutralizing the color altogether. Think about converting a colored picture to grayscale and you will understand what may be happening! This property of color is called Saturation.
Now beyond Luminosity and Saturation lies the Hue of color. You can have a blue that’s dark or light, and even vibrant or neutralized. But you can also have a green, a red, an orange, a yellow, or any other color with those same attributes. This red, green, yellow, or blue property is nothing else but the Hue of the color.

Color is a fascinating subject; a subject that evokes enough creativity and pickles the minds of many. If we were to pause looking at color as a creative subject for just a brief amount of time, we would be able to explore it from a different perspective, the perspective of science! This color science will open new avenues for us to understand why colors behave in certain ways.

While computers can easily understand the fact that you mix red and green to end up with yellow, that’s some strange logic to us humans which we shall never comprehend!
How can we stay within the RGB color model, which computers understand, and mix colors more creatively to use a method which we humans can understand? This need for a more creative model gave birth to the HSL (Hue, Saturation, and Luminosity) color model.

While we learned the basics about RGB colors, that constitute portions of Red, Blue, and Green—what we need to know is that there is so much more to learn about them. Did you know that there are two ways in which individual RGB color values are expressed? The most common way is using decimals.
But have you run into color values such as FF0000 or 006699? These six digit values that combine number and alphabet characters are hexadecimals. Now hexadecimals express the same values as decimals—but unlike decimals that need 9 characters to describe the three colors, R, G, and B, hexadecimals need only 6 characters.
