I have a hex colour #0d152c, which is a corporate colour, when this is converted / printed in CMYK the colour doesn't convert well when printed and looks a bit washed-out because obviously CMYK has a lower colour range.
Is there a way of taking a hex colour and finding a CMYK colour that is reasonably close that will look good when printed (I think this would be called a spot colour?). When I change the colour mode in Adobe illustrator the colour on screen doesn't change, and is still rendered on screen as an RGB colour because that's what my monitor uses.
I am new to Graphic Design so please be kind :)
