Well . . . If your paint is not metallic then painting it the same shade, but metallic, is not painting it the same color at all. Doing a color change right on a Pagoda entails taking a good bit of the car apart, to repaint under the hood and in the engine compartment, the dashboard, and all the hard to reach areas on the door sills, door posts , doors and door hinges. So my inclination would be to stick with the original color, regardless of the advice offered by your classic car paint shop. I they are any good they should be able to spectroscopically match the color from an unstained, unfaded area like the dash board or one of the door posts, and the new paint should seamlessly match the areas that don't need painting without any overspray.
