Does anyone knows how to avoid the change of the colors in the images wordpress made after the uploading?
If I export an illustration in safe colors and upload (black and grey illustration), the colors of the Thumbnails change.
Left one, the mew image from wordpress, right one the original color.
I export as sRGB from adobe illustrator .
This was the first search result I found: http://www.wpbeginner.com/wp-tutorials/how-to-fix-image-color-and-saturation-loss-in-wordpress/
Yes, I read some of them. All say the same but those tutorials maybe are for jpb, because I try with a .jpg file and it works, but if I try with a .png, do not works. The colors are a litle different of the original one. A very dark gray instead of the original gray.
Regardless: this isn’t a Pressbooks issue. You are more likely to find specific answers to you problem on the WordPress forums: https://wordpress.org/support/welcome/
Is your PNG translucent?
I know is not a PB issue, but is a situation that will afect to all the PB users if they upload a .png image.
The .png are not translucent.
I will keep searching a litle more. I did ask in WP, i´m waiting an aswer.
