To get a physalis colour (that warm golden-orange like the fruit husk), you’ll mix your emulsion base using a balance of yellow oxide and a touch of red oxide.

What “physalis colour” look like? It’s a rich golden-orange, not too bright like pure orange, and not too dull like brown. Think of a warm sunset orange with a slightly earthy tone.

Mixing formula (practical guide)

• Things to consider during colour matching:
  Always add colourants little by little - it’s easy to go too dark.
• Let the paint dry before judging the colour (wet paint looks darker).
• If it becomes too dark, add more white.
• If it looks too yellow, add a bit red oxide

Another name for physalis: Some colourant brands even label it ochre orange, sunset orange, Golden orange tone, Muted orange or earthy orange.

PROCEDURES IN PRODUCTION OF PHYSALIS EMULSION PAINTS:
Step 1 - Pour clean water into an empty tank.
Step 2 - Add calgon stir and empty the sac of titanium dioxide into the solution. In this production, we are using 100g of titanium dioxide for a 20-liter bucket.

Step 3 - Put on the electronic motor on, with it shaft deep into the tank for agitation and grinding of the tio2 particles. (Allow to grind for 30-45 minutes until a fine solvent is obtained)

Step 4 - Shading technology is introduced at this point. In this production, we are using 250g of red oxide and 1kg of yellow.

Step 5 - Empty sacs of calcium trioxocarbonate IV (caco3) into the mixture, followed by the addition of water into the mixture to prevent the accumulation of the caco3 particles on the shaft.
Step 6- The introduction of additives is employed at this stage (i.e., the introduction of  colour pigments if a specific colour is required apart from white,

Step 7 - Acryli  is added immediately as an emulsifier
Step 8- A measured quantity of hydrocellulose ether is mixed with water and then poured to thicken the film, flowed with addition of genniple.
Step 9 - biocide or formalin is then added to stop bacteria growth and defoamer or kerosene for foaming control.)
Step 10- The addition of ammonia stirs a few seconds and is followed by packaging.

Simply put use: 

• 100g of titanium dioxide 
• 250g of red oxide
• 1kg of yellow oxide 

Recall that this measurement is for 20 litres bucket of emulsion paint, any increas in titaniu dioxid will alter the shade
