In the RGB Color Model, the R represents Red, G represents Green and B represents Blue. These three are the primary colors of light. And all the other colors are formed by the combination of these three colors, and it is thought that the mixing of many different colors could not create these three colors.
Agreementing to some studies, each primary color's intensity can vary from 0 to 255, which means for each color, you can produce 256 shades—with three primary colors, resulting in almost 16,777,216 colors.
If R = 0, G = 0, B = 0, then you will get black, and if R = 255, G = 255, B = 255, then you will get white. That Color Model is additive color model.

In the HSV Color Model, the H represents the Hue, S represents the Saturation, and V represents the Value (Radiantness). Therefore, in this color model, the color is represented by the Hue it carries, how much saturated (Saturation) it is, and its Radiantness.
The HSV Color Model represents the color in an intuitive way, that how colors relate to humans.
In that color model, the Hue takes the value from 0 to 360 degrees (In the color wheel, the Red falls at 0 to 60 degrees, Yellow falls at 60 to 120 degrees, Green falls at 120 to 180 degrees, Cyan falls at 180 to 240 degrees, Blue falls at 240 to 300 degrees, and Magenta falls at 300 to 360 degrees). The Saturation and Radiantness take value from 0 to 100 percent.
The HSV Color Model is the alternative representation of the RGB Color Model.

The RGB Color Model is the most popular color model to mix and create colors. Red, Green, and Blue are the primary colors of light, and all the other colors are formed by combining these three colors and various intensities. But the problem with that color model is that people do not understand the colors as the mix of these three colors.
If the computers graphic students have to create color like greenish-blue. That becomes quite tricky for the students to develop such color. Because in the RGB Model, you do not know the actual intensity that each color requires to create such color. How you should make it appear lighter or darker? These are the reasons that RGB Model unable to answer.
Therefore, the artists develop another system to define the more understandable colors for humans, known as HSV Color Model. That color model is also called the HSL (Hue, Saturation, and Lightness) Color Model.

Manually converting the color from one color model to another is quite tricky. Therefore, web developers develop several online tools that are available that convert RGB to HSV.

For converting the RGB color value to the HSV color value, do the following steps.

• Open the RGB to HSV Color Converter Tool.
• Enter the Red, Green, and Blue color values.
• You can also use the "Color Palette" to select the required color.
• Click on the "Convert to HSV" button.
• It will convert the RGB color values to the HSV color values.
• Click on the "Copy" button and paste it into the desired location.
• In the end, a list of a wide range of commonly used colors is given—their name. HEX, RGB, HSV, and CMYK color codes are provided in front of each color.
• The search facility is also provided to search the color by using its color name, or HEX, or RGB, or HSV, or CMYK color codes value.

Note: You can also convert HSV color values to RGV color values using HSV to RGB Color Converter.
