Can I varnish over the hard-to-find-color of flat paint in the kitchen to make the walls shiny and more cleanable?

You could apply a urethane, but check with your paint store about compatibility over the existing paint.
But why not get the color matched, and repaint the walls with an eggshell or satin enamel? Most paint stores have sophisticated color matching systems that can figure out the formula for just about any sample you bring in.
