  1. The Shades of Grayscale

  2. Shades of Gray In real life, there are actually more than 500 shades of gray. Our human eye could not distinguish all of it but there are at least 30 shades that we can see. Some may be gifted and can see around 50 but normally, 30 shades are visible.

  3. What are the different shades of Gray? Isn’t it amazing how our eye can detect around 10 million unique colors but can only distinguish 30 shades of gray? These shades can also be categorized in four parts – the Achromatic grays, off-grays, the cool grays, and the warm grays.

  4. What’s the difference between the three categories?

  5. The first category shows you different shades that have equal RGB mixtures (red, green and blue). The second type, the off-grays have unequal colors combined while the cool grays have other hues surfacing such as bluish, violets or greenish colors. The last category, the warm grays, have brown or pinkish shades surfacing its gray color.

  10. Why some users prefer grayscale? In basic reasoning, grayscale makes everything simpler and therefore having smaller data. With this said, your computer will be able to do more complex processes faster. To elaborate further on the data, let’s list it down one by one.

  11. Reasons why it is preferred 1. PDF files and images automatically becomes smaller in size and gets compressed when converted to grayscale. It simplifies the code in the file, allowing your computer to do faster. 2. In image processing, having a grayscale image helps identify edges and texture, helping users by identifying noise in the image. 3. Colors have 3 dimensions or 3 layers – R, B and G. Grayscale meanwhile have only 2 – black and white. In programming, there are certain codes applicable only to 2 dimensional images, hence the preference for a grayscale image.

  12. Reasons why it is preferred 4. In photography, having images in gray sets the mood and the tone of the photo. It also emphasizes objects and depth when needed to.
