On this webpage I found this:

The study found that “globs” in the brains of monkeys reacted differently to colored stimuli, and reacted based on color. The brain was most triggered by specific colors (red, then green, then blue) and colors with the most saturation. What this tells us is that these colors immediately impact a user and draw attention.

Question: Do humans show similar increased neural activity to some colors?

Then I found a perception curve in this webpage A perception curve

While this curve tells that yellow and green are seen before other hues while red and violet are difficult to perceive; I am not sure if yellow and green elicit more neural activity in the brain.

Anything to say on this matter?

The paper from Stoughton & Conways (2008), where the linked Design Shack webpage refers to, explains that in the visual nucleus in the brainstem (LGN) as well as in the primary visual cortex, most of the color-selective neurons are selectively responsive to colors in the red-cyan axis (Fig. 1).

This indeed means that these colors evoke more brain activity in these regions of the brain.

Note that a perception curve mentioned on the linked D'Source webpage is nonsense terminology
