Answer from Youlton Niyozi[newbie]
Invert colors
The Invert command inverts the colors of an image. You can use it during the edge mask process to sharpen and apply other adjustments to selected areas of an image.
Note: Because color film contains an orange mask at its core, the Invert command does not create accurate positive images from scanned color negatives. When scanning film, use the correct settings for color negatives.
When you invert an image, the brightness value of each pixel in the channels is converted to its inverse value on a 256-step color value scale. For example, a pixel in a positive image with a value of 255 gets a value of 0, and a pixel with a value of 5 gets a value of 250.
Do one of the following.
Choose Image > Adjustments > Inverse.
Choose Layer > New Adjustment Layer > Inverse. In the New Layer dialog box, click OK.
Answer from Oleg is still the same[guru]
Choose Layer > New Adjustment Layer > Invert. In the New Layer dialog box, click OK.
If you want to invert (invert) the colors of an image using MS Paint, then keep in mind that in Paint 6.1 (Windows 7) and later versions of this program, the procedure for inverting colors has been changed - inverting colors is still quite easy, but the algorithm action is not immediately obvious. To quickly invert colors, press Ctrl+Shift+I. This article will tell you how to invert colors in new and old versions of Paint.
Steps
On Windows 7 and later versions of the Windows operating system
- If you want to invert the colors of a specific area of the image, select only that area.
-
Invert the colors. To do this, right-click on the selected image (or selected area of the image). In the menu that opens, find and click “Invert Colors.” The colors of the selected image (or selected area of the image) will be immediately inverted.
- To quickly invert colors, press Ctrl+Shift+I.
In Windows Vista and earlier versions of the Windows operating system
-
Open the image you are editing in MS Paint. This can be done in two ways:
In the top toolbar, click “Image” – “Invert Colors”. This will instantly invert the colors. Reversed colors are scientific additions to the original colors. When inverting colors, the yellow ball will turn into blue (instead of purple as with the traditional addition).
- To quickly invert colors, simply press Ctrl+I. Please note that this keyboard shortcut only works on Windows Vista and earlier versions of Windows.
-
Save the image. To do this, click “File” – “Save As”. Enter a file name and select its type (if necessary). Save the edited image in a folder that you can easily find when needed. Then click "Save".
- Instead of launching Paint, open your My Documents folder or your pictures folder, right-click on the picture and select Open With - Paint.
- To select a specific area of the image, use the Selection Shapes tool.
- To see a consistent image, zoom in on the inverted color image and stare at the center of the image for thirty seconds. Then quickly look at the empty white wall. You will see the picture in original colors. Keep in mind that this method works better with photographs and larger images.
- Press Ctrl+I (or Ctrl+Shift+I on Windows 7 and later operating systems) to quickly invert colors.
- To quickly open an image, press Ctrl+O.
- Press Ctrl+Z to undo up to 3 previous actions.
- The most common graphic file formats are BMP, PNG, JPG, GIF. In most cases, the PNG format guarantees a minimum file size without losing image quality. Select the JPG format if the image you are editing is a photograph, although some users find that choosing the JPG format in Paint will reduce image quality. If you intend to post an image on a website, use a good image editor to reduce the file size.
- Look online for interesting images whose colors can be inverted. Please be aware that content online may be protected by copyright; In theory, you can edit any image as long as you don't intend to sell it, redistribute it, or attribute credit to it.
- You can invert colors in any graphics editor. The procedure will be different (from Paint), but the result will be the same.
- If you're using the Freestyle Tool, drag the selection across the image and then return it to its original position. This is the only way you can invert the colors of the selected area (otherwise the colors of the rectangular area will be inverted, not the freeform one).
Warnings
- If you cannot find MS Paint, then your computer or laptop is running an operating system other than Windows. In this case, use any other graphic editor, which may be even better. Graphic editors are available both paid and free. Look for them on the Internet.
- In Windows 7, right-click on the image to invert the colors.
- If you click Save As instead of "Save As", the original image will be overwritten by the edited image. Don't do this if you want to save both the original image and the edited one.
- If you hold down the CTRL + I (or CTRL + SHIFT + I) keys, the colors will flash rapidly. Be careful: this may cause headaches!
What you will need
- Image to edit
- Microsoft Paint
Please note that the procedure for inverting colors has been changed. Don't look for the Invert Colors tool in the top toolbar (as you did in Windows Vista and earlier versions of Windows). Starting with Paint 6.1, you can invert colors by right-clicking on a selected area of the image. New versions of Paint, in which the described procedure works, are pre-installed in Windows 7, 8, 10. Of course, this innovation will be difficult for people who have been inverting colors for years using the button on the top toolbar, but don’t despair - invert colors in Paint still pretty easy.
Select an image. If you want to invert the colors of the entire image, select the entire image. To do this, in the top toolbar, click “Select” - “Select All” or use the “Selection Forms” tool.
Starting with iOS 7.0, iPhone introduced color inversion. This function completely reverses the colors - black becomes white, white becomes black. This mode helps people with low vision who need high contrast to read.
You may ask, why do we need this function if we see well? I found a great use for it. I wrote that I really like to read various articles and news at night. But my other half prefers complete darkness to sleep, and the glow of the phone irritates her. In that article, I was able to reduce the screen brightness further than the standard phone settings allow. But to be honest, brighter text is easier to read. I continued my search for the optimal mode for reading at night.
I found it! This is an inversion of color. The entire background turns black and the black letters turn white. At the same time, it is very pleasant to look at the phone in the dark, the glow does not hurt the eyes, the letters are very easy to read, and at the same time there is much less light, the eyes do not get tired at all. My wife is completely satisfied with this.
How to enable this feature:
1) Settings – Basic - universal access – Color inversion on/off
2) For more convenient use, I configured this function to triple-click the Home button: Settings – General – Accessibility – Keyboard shortcut – Invert color
During the day, the “Invert Color” mode is not convenient to use, but at night it is very comfortable for the eyes to read text on the iPhone screen.
P.S. This mode completely inverts all colors, not just black and white, so all pictures and videos are also inverted. Recommended for reading black and white text only. Take care of your eyesight.
P.P.S. Trying to take a screenshot of the screen in color inversion mode will not yield any results. The screenshot will be taken in normal colors.
