HSL vs. HSV

In RGB color space, HSL and HSV are two related representations of points that aim to express perceptual color relationships than RGB more appropriately while still being computationally straightforward. The acronyms HSL and HSV are hue, saturation, lightness, and value, respectively.

Alternatives to the RGB colour model, such as HSL (for hue, saturation, lightness) and HSV (for hue, saturation, value; also known as HSB, for hue, saturation, brightness), were developed in the 1970s by computer graphics researchers to be more in line with how human vision perceives color-making characteristics. 

In these models, neutral colors that range from black at the bottom to white at the top form the central axis, around which colors of each hue are grouped in radial slices.

A color with the most value or brightness in HSV is comparable to shining white light on a colored object (for example, lighting a strong white light on a red object allows the object to still appear red, only brighter and more intense). In contrast, a color with the most lightness in HSL is pure white.

The HSL color model nonlinearly deforms the RGB color space. Let's examine a few programs that include it in their operations:

• Paint Shop Pro
• MSPaint
• ImageMagick
• Inkscape.
• Adobe Photoshop (also incorporates HSV)

Applications that use both HSV and HSL:

• Pixel image editor
• Pixia
• Bryce
• The GIMP (HSV for color selection, HSL for image color adjustment)
• Photoshop (HSV for color selection, HSL for image color adjustment)

HSL and HSV are defined mathematically by transformations between the r, g, and b coordinates of colors in RGB space and the h, s, l, and v coordinates of the HSL and HSV spaces.

Understanding the Meaning of Each Code

Three primary colors are used in HSL color codes: red, green, and blue. Red is associated with warmth, while blue is associated with coolness. Green is associated with neutrality.

Using Color Codes Effectively

To use these color codes effectively, you must understand how each one works. Here's an overview of what each code means:

Red – Warmth

Green – Neutrality

Blue – Coolness

Here's everything you need to know about HSL color codes.

The HSL (hue, saturation, lightness) model has three different ways to represent color. They are as follows:

• HSL - Hue, Saturation, Lightness
• RGB - Red, Green, Blue
• CMYK - Cyan, Magenta, Yellow, Black

Web designers and developers use the first two, while print designers use the last.

What Is Hsv? How To Calculate It?

You can calculate HSV by using the following formula:

HSV = (Number of days since last period) x (Number of episodes per day) / (Number of days in cycle)

HSV = Saturation x Value x Hue

HSV stands for hue saturation value. This is an indicator of how much color there is in a picture. A higher number means more color.

• Saturation – The saturation percentage of the color. The percentage of red, green or blue in the color. In order to calculate HSV, you need first to determine what the colors are in the image. A photo has three different colors: Red, Green and Blue, and each color have its own percentage.
• Value – The brightness of the color.
  A value of 100% means that the color is pure white, and a value of 0% means that the color appears black.
• Hue – The hue angle of the color.
   

A high saturation means the color is very bright, while a low saturation means that the color appears dull.
