Inside the pyramid.
A certain "color" hovered high in the air. Its top resembled a spherical object, while its bottom cascaded downwards like a waterfall, "expressing" a unique radiance.
Pink, purple, red…
It was hard to describe in existing words, and even transcended the definition of spectrum itself.
These colors were both pure colors and living entities.
The colors made Han Dong uncomfortable as they met his gaze.
Whether it was agitation, anger, or sorrow... All sorts of emotions were stirred by these colors.
"That phosphorescence that emerged from the well gave people an odd sensation, a feeling of impending doom. This feeling had far surpassed any scene they could conceive of; that color was not just flickering, but gushing out of the well. When this intangible flood composed of unrecognizable colors left the well, it seemed to flow straight to the sky."—H.P. Lovecraft, The Colour Out of Space.
