When I apply a color to the fill or the stroke, a HEX code will appear in the XML edit section.

How can I have a DECIMAL representation like this:

fill:rgb(82,128,200);stroke:rgb(255,0,80);stroke-width:48.6425209;stroke-linecap:butt;stroke-linejoin:miter;stroke-miterlimit:4;stroke-dasharray:none;stroke-opacity:1;paint-order:normal;fill-opacity:1

Whenever I enter a decimal value, as soon as I click on the SET button, the values change to HEX.

Thank you

I'm not sure if Inkscape can do that... maybe an extension that saves the file that way. 

You can place a feature suggestion/wishlist request on the issues list: https://inkscape.org/forums/beyond/how-to-report-bugs-or-request-new-features/

Thank you Tyler.

I read somewherenthat if one types in an rgb value, Inkscape will keep it.

I found that if you manipulate data of an svg fike outside of Inkscape, Inkscape will keep the rgb vales you enter but only if Inkscape opens a file that contains the rgb value and not if you enter rgb values within Inkscape.

So if anyone knows how to edit and maintain rgb value inside Incscape (xml editing), please post an answer here.

Thank you.

You could open the .svg file with a text editor, if the areas to be colored are not too many.

Unfortunately there are close to 200 elements.
