Links color

Converting other formats to epub or mobi, Calibre changes color of links to blue,no matter what the color of links was in the original file.
Would it be possible to have an option of keeping the original color?
As it is now I am forced to use Sigil to fix the colors after the conversion to epub & convert to mobi with Kindlegen instead of Calibre.
It would be much more convenient to do everything in Calibre.
