Ingredients & Supplies
Creating professional-quality watercolors requires only a few simple ingredients, most of which you likely already have in your kitchen:
- Baking Soda: Acts as the base pigment carrier and provides the characteristic chalky texture of watercolors
- Cornstarch: Functions as a binder that helps the paint adhere to paper and dry to a smooth finish
- Food Coloring: Provides vibrant, customizable colors (gel or liquid both work)
- Water: The activating agent that makes the paints workable
- Ice Cube Tray: Perfect for creating individual paint portions (silicone trays work best)
- Small Bowls: For mixing colors and creating custom blends
- Measuring Spoons: For accurate ingredient proportions
- Small Whisk or Fork: For mixing ingredients thoroughly
- Paintbrushes: Any basic set will work for initial testing
- Watercolor Paper or Thick Paper: To test and use your homemade paints
The Recipe: Step-by-Step Guide
Follow these detailed instructions to create your own vibrant, non-toxic watercolor paints:
Basic Watercolor Paint Formula
- 2 tablespoons baking soda
- 1 tablespoon cornstarch
- 8-10 drops of food coloring (adjust for desired intensity)
- 1-2 tablespoons water (added gradually)
- Mix Dry Ingredients: In a small bowl, thoroughly combine 2 tablespoons of baking soda with 1 tablespoon of cornstarch. Use a whisk or fork to ensure even distribution and break up any lumps.
- Add Color: Add 8-10 drops of your chosen food coloring to the dry mixture. For more vibrant colors, you can add up to 15 drops, but start conservatively as you can always add more.
- Gradual Moistening: Slowly add water, one teaspoon at a time, while continuously mixing. The key is to add water gradually to achieve the right consistency.
- Test Consistency: The mixture should resemble thick paint – not too dry that it crumbles, but not so wet that it’s runny. You’re aiming for a texture similar to yogurt or thick pudding.
- Adjust as Needed: If the mixture is too thick, add water one drop at a time. If too thin, add a small amount of additional baking soda and cornstarch (maintaining the 2:1 ratio).
Setting in the Ice Cube Tray
- Prepare Tray: Ensure your ice cube tray is clean and dry. Silicone trays work best as they’re flexible and easy to remove paints from.
- Fill Compartments: Spoon the prepared paint mixture into each compartment of the ice cube tray. Fill each about 3/4 full to allow for expansion during drying.
- Smooth Tops: Use the back of a spoon to smooth the tops of each paint portion for a uniform appearance.
- Drying Time: Allow the paints to air dry completely, which typically takes 24-48 hours depending on humidity. The paints are ready when they feel completely dry to the touch and have a matte finish.
- Storage: Once dry, the paints can be stored indefinitely in the tray or popped out and stored in airtight containers.
Creating Custom Colors
One of the most exciting aspects of homemade watercolors is the ability to create custom colors and experiment with color theory:
Color Mixing Guide
- Orange: Mix 2 parts red with 1 part yellow
- Green: Mix 2 parts blue with 1 part yellow
- Purple: Mix equal parts red and blue
- Brown: Mix all three primary colors in varying proportions
- Pastels: Use less food coloring and add a small amount of white food coloring or titanium white pigment if available
- Earth Tones: Mix brown with small amounts of other colors for muted, natural hues
- Metallic Effects: Add a tiny amount of edible gold or silver dust for shimmer (ensure it’s art-safe)
Color Intensity Tips
- Gel food coloring typically provides more vibrant colors than liquid varieties
- Start with less colorant and gradually add more until you achieve the desired intensity
- Colors will appear more muted when dry but will reactivate brightly when wet
- Label your colors as you create them to easily replicate favorites
