These are all hearts differently hand written as "LM" using the colors from the website you attached. If I may suggest since there seems to be a fine line between creating neutral colors and the need for colors that depict 'life'...it seems that you are giving the viewpoint of Life with Love. The very soft pale turquoises as on your website..along with pale hues of oranges or peach....or hues of green would do that nicely.
