That colour looks very close to Farrow & Ball Red Earth No64 or Book Room Red No50. Hard to tell exactly in the light. :)

Thank you for your question. The wall paint shown here is
Behr Royal Liqueur (PPU2-19), available through The Home Depot.

Before choosing a paint color, it’s a good idea to view color
swatches or even try a small paint sample in your space to understand how the color
will appear in that setting. In this kitchen, the large windows let in an
abundance of natural light. The amount and color of the lighting can influence
how a color looks.
