One way of toning down a color is to add just the smallest hint of it\'s opposite. This greys the color but, if you use the same tone, doesn\'t darken it. So for blue mix it with a brush you dabbed into orange and brushed almost clean (like you would when dry brushing). This will add a touch of the orange (becareful that the orange is as light as the blue) without being too much. You can always do it again if the blue is still too bright. go slow untill you have the color you want.
