People have been inverting the colors in photographs ever since photography was discovered. But back then, color inversion meant working with various chemicals and film negatives in a dark room. Today with digital photography and the technology available, it is much easier to invert the colors.
In this article, we’ll look at several color inversion methods. You’ll learn to invert an image’s colors using Photoshop, online web tools, and phone apps. Read on and find out why you might want to invert the colors on a picture.
What Is Color Inversion?
Color inversion in an image means flipping the colors to their opposites on the color wheel. The green will become magenta, red will become blue, and yellow will turn violet. The brightness of each pixel will also convert to its corresponding value.
The color wheel was invented to show the relationship between the colors. It was first created by Isaac Newton for his experiments in optics. Since then, it has been updated to suit the needs of scientists, designers, artists, photographers, videographers, and others.
To have a better idea, here is what a color wheel looks like:
You might wonder if it is possible to do the color inversion on black and white photos since they have no color. The answer is yes, but in this case, color inversion means that the light areas become dark, and the dark areas become light. In colored images, the colors are inverted to their complementaries. There is no loss of color saturation or brightness.
Why You Might Want to Invert the Colors in Your Photos
There are different reasons why you might want to invert colors on your photos. Some are purely aesthetical. People simply find pictures with inverted colors interesting and fun to look at. However, color inversion can also help people who see colors differently.
Color blind people also find color inversion useful. Color blindness doesn’t mean that a person sees the world in black and white. There are different types of color blindness, and people with this condition often see colors differently. Inverting the colors may help them see colors where they thought there were none.
Color inversion not only affects the colors of an image but also increases the contrast and enhances the details. This might be useful for people whose vision is impaired. Since it also darkens the light parts, it can reduce eye strain by eliminating blue light.
