Gradient mesh background for a hero section

A moody, atmospheric gradient mesh background rendered in ultra-wide 2400x1350 resolution. The composition is left-biased: the left two-thirds carry the energy while the right third fades into a quiet, near-black canvas suitable for overlaid headline copy. Anchoring the center-left is a rich indigo (#4F3FCF) blob that bleeds outward into a deeper purple (#2A1F6B) at its edges. Above it, a softer violet (#8B7FE3) blooms and diffuses, creating a sense of atmospheric haze. Offset below and slightly to the right, a teal-green accent (#3FCFB8) glows in a loose organic shape — its edges feather into the indigo, creating a subtle cyan transition zone where the two hues meet but never collide. A small, high-intensity coral node (#FF7A6B) sits near the upper-left quadrant, acting as a focal point that draws the eye without overwhelming the palette. Its presence is balanced by the warmth it introduces against the cool dominant tones. The base canvas underneath is a near-black (#0A0A14) that deepens toward the edges and corners, creating a natural vignette that pushes the color nodes forward. Film grain is applied at low opacity (around 4%) to break up any banding that digital gradients tend to produce at scale. All shapes are loose, painterly, and feel hand-crafted — no sharp edges, no geometric primitives. The overall feeling is premium, calm, and confident: something you would see behind the headline of a Series-B SaaS homepage. The color nodes transition smoothly without muddying into gray in their overlap zones; saturation holds even through blends. The right third of the composition deliberately quiets: color saturation drops, brightness lowers, and the canvas fades toward pure black, leaving an uncluttered space for 2-3 lines of large white display type.
