Decorating techniques make use of the most unexpected local resources. Somewhere around the Mediterranean,
a nameless visionary was the first to use an olive oil plaster finish to embellish the home.
This simple preparation is applied in one or two coats.
Over a Venetian plaster finish, it brings out the texture and adds color.
Mix the juice of half a lemon with one liter of olive oil.
Grind about 50 g of pigment using a painter's knife and ceramic tile (or even better, marble).
Form a "mountain" with the pigment and make a hole in the middle; carefully pour in a little olive oil.
Mix and crush using the knife. The mixture should be smooth and velvety.
Once the pigment has been finely ground and blended, add it to the olive oil and lemon juice. Mix thoroughly.

Apply with a wide brush, avoiding any overlapping or splattering.
The plaster will "drink in" the tinted oil, and the final finish will be matte and soft to the touch.
To intensify the effect of depth and texture, you can use a second coating, but the color can become quite dark.
The pigment used in the example is "Charron blue".
