How to get oxblood colour paint production

HOW TO PRODUCE OXBLOOD EMULSION PAINT 

To produce oxblood paint, mix red oxide pigment with black oxide pigment, incremental amounts of black oxide and red oxide pigment will create a rich, dark brownish-red shade.

Using pigments such as iron oxide (red ochre) along with black pigments can achieve this color. The key is to start with a red base and gradually darken it. 

Key Steps for Producing Oxblood Paint:

Base Color: Start with a deep red pigment or base, such as maroon, crimson, or red oxide, rather than a bright primary red.

Darkening Agents: Gradually add small amounts of black or dark brown (like burnt umber) to the red base.

Pigment Combination: Oxblood can be achieved by blending red and black oxide pigments to get the desired brownish-red tone.

Mixing Technique: Stir thoroughly between additions to check the color depth. For a deeper, more violet-leaning oxblood, a tiny amount of blue can be added to the red base.

Testing: Apply a test patch and allow it to dry completely, as the color may change after drying.
