Abstract matte gradient surface close-up

A softly lit 3D-rendered abstract surface stretches edge to edge, as if viewing a gently rounded matte wall from very close, its colors melting from pale mint at the bottom into soft sky blue and then a whisper of cool white toward the top in a vertical gradient so slow and blended that there are no discernible boundaries, only a calm sense of upward lightness; slightly left of center, a tall, diffuse column of more luminous mint-blue rises, its edges indistinct and misty with a digital airbrush feel, suggesting a soft volumetric glow emerging from behind the blur, while the right side of the frame holds a quieter, more uniform mix of blue-green that remains visually restful; the entire surface looks like pigment pressed into smooth plaster, rendered in 3D with almost no visible texture beyond very large-scale, barely-there patches of marginally lighter tint, and the contrast everywhere stays low, with the deepest tones only mildly deeper and never dark; roughly seventy percent of the frame, especially the central and upper-right areas, stays extremely gentle and even, a serene matte field with no stripes, shapes, or any hint of letters or icons.
