Article: Make sure that you have enough paint to complete the coverage needed with this shade of dark blue.  Once you have mixed the perfect hue, it could be difficult to match this shade a second time.  It’s always better to make more dark blue than you need rather than run out.  If you do not complete your project in one sitting, you can store your excess paint in an airtight container like a plastic container you would use to store leftover food. Consider wetting a paper towel or sponge and placing it in the bottom of your container, or using a Sta-Wet Palette to keep your paint from drying out.
