blue purple red -> black red red

i know done in css or javascript in way not know how it. i've been messing css filters , putting div on top of color, nothing rid of blue.

does know how / possible?

you try using css filters however, don't think there filter specific colour , browser compatibility limited. https://developer.mozilla.org/en/docs/web/css/filter

alternatively use svg image allows modify parts of image using css think svg files can pretty big large images... think can use adobe illustrator save files svg. http://www.w3schools.com/svg/tryit.asp?filename=trysvg_myfirst
