Before converting images, it’s best to do the following:

For example, you may have an old scanned photo in grayscale mode in which you want to add color, so you would need to convert it into RGB mode.

You might want to convert into a different mode for several reasons. When you choose a different color mode for an image in the Edit workspace (Image > Mode > ), you permanently change the color values in the image. For extensive editing, you should convert temporarily into RGB mode. Limited editing is available in this mode.

By limiting the panel of colors, indexed color can reduce file size while maintaining visual quality-for example, for a web page. If a color in the original image does not appear in the table, the program chooses the closest one or simulates the color using available colors. When converting into indexed color, Photoshop Elements builds a color lookup table (CLUT), which stores and indexes the colors in the image.
