Color value of image_html/css_WEB-ITnose

The problem I have encountered before is that some pictures cannot be opened in IE8 and lower version browsers. However, through packet capture, it is found that the bytes and other data of the file are completely normal, which basically shows that the file is loaded. OK, the problem lies in the browser rendering, but I really can’t figure out where the problem lies, and I can’t find a corresponding explanation on the Internet. After verification by many parties, I found that it is caused by the color value of the picture. Simply put, it is RGB and CMYK. caused by the difference.

RGB: Display basic color mode

CMYK: Printing color mode

The lower version of IE browser is not compatible with CMYK color values, so the image cannot be rendered
