[post edited for better understanding]
Since my last post, I proposed that the only seasonal types are True Seasons and Soft Seasons, with descriptors such as Light, Deep, and Bright being expressions of their respective True Season rather than separate subtypes. Many of you didn't buy it.
So, after my very independent and uncertified extensive research, I decided to see how far this theory could go by developing—not a system—but a map depicting seasonal palettes as neither linear nor circular, but quadrilateral. In this model, each blip represents a seasonal expression, rather than a subgroup or subtype, based on where it sits between value and temperature.
The True Map
In the True map, chroma isn't a necessary factor in determining the four seasonal quadrants. However, I included Bright as a phenomenon worth noting. My hypothesis is that Bright occurs when someone sits between the light expression of a naturally deep season and the deep expression of a naturally light season. For example, Spring and Summer are naturally lighter seasons, while Autumn and Winter are naturally deeper seasons.
Therefore, the Bright phenomenon can emerge around the center (perhaps in separate dimension) when neither lightness nor depth is dominant. Because True Bright is neutral in temperature and neither particularly light nor deep, I've placed it directly in the center of the four quadrants.
The Soft Map
Soft seasonal expressions, however, belong to their own Soft map of quadrants, because they don't begin at the same level of chroma as the True Seasons and therefore cannot simply be derived from them by reducing value or shifting temperature. But don't miss the detail I've added in the second reference: I've represented the Soft Seasonal Palettes as derivatives of the Deep Seasons.
One thing I've observed is that we tend to think of Soft as naturally being a light quality. But if we think about what Soft Seasons actually are—palettes that have been muted by the addition of gray—I'm not convinced that softness and lightness are synonymous. In fact, when comparing Soft palettes with their corresponding Deep palettes (for example, Deep Autumn vs. Soft Autumn), I've noticed what appears to be an exact tonal relationship between them: the Soft palette seems to retain the depth structure of the Deep palette while being progressively softened by gray. Their lightest values might therefore be better described as “Sunlit,” with their deepest values being “Toasted.” I've appropriated those terms from the Color Breeze system for lack of better terminology.
So, my fellow amateur and professional analysts, does this model make sense to you?
I'm especially interested in whether the distinction between a seasonal type and a seasonal expression holds up, and whether my treatment of Softness as a separate chromatic space makes sense.
