The root color of Antonio Marras

From the history of color usage from Antonio Marras, it isn't hard to know that Antonio Marras has been repeatedly using the color of Black, White and Red.

What is color theory beneath it? Monochromatic? Primary color? NO.

If you have a profound study on the biography of Antonio Marras, you would know that those three colors are actually the core colors from the flag of Sardinia.

Besides, culture of Sardinia deeply influences his design and color used.

You might say, why the combination of Red, Black, and Red could only inspired flag of Sardinia, but not other countries flag with same color pattern.
Designer uses the color combination to remind of his own country by both color selection and color ratio.
For example,
You could not the be reminded of Germany by using the color of Red. Black, and White, as the color combination of traditional Germany is Black, Red, and Yellow.
Nonetheless, you might argue that the color combination of Black, Red and White are also the core color consisted in the Egypt country flag. Thus, could it possible Antonio Marras using such color combination to remind the culture of Egypt?
I could say that that answer is No. Other then the color selection, color ratio is another skill to express messages. The color ratio of Egypt flag of Red, Black, and White are in equal ratio, but Sardinia flag is in which under the ratio of Red: 20 Black:30 White:50. Accordingly, the color ratio in Antonio Marras Design follows similar color ratio.
To conclude, the color combination and color ratio of Antonio Marras Designs successfully deliver the conceptual message of his own country.
