OrangeReal 90 applies a strong realism lift over the color base (alpha = 0.90) on a vivid-color base: near-photographic output where vivid color only lingers in accents and mood.

[Recipe] Add-difference merge on UNet only: Nova Orange XL REX v1.0 + 0.90 x (Nova Reality XL v9.0 - PerfectDeliberate v10). VAE and text encoders are inherited from Nova Orange. Illustrious-family checkpoint, fp16 safetensors, no baked LoRA.

[Why this direction] Nova Orange XL gives rich, saturated, eye-catching color. Adding the realism delta (Nova Reality minus PerfectDeliberate) injects photographic skin, light falloff and micro-contrast without washing out the color identity. The four rungs stay visibly apart instead of collapsing into one look.

[Series] OrangeReal IL: 30 / 60 / 90 / 120 on the same vivid-color base, one direction only - toward realism.

[Recommended settings] Euler a, 24-28 steps, CFG 5.0-5.5, 832x1216. Hires fix above 1.25x helps skin detail.

[Known limitations] At alpha 1.20 skin texture and contrast are pushed hard, so drop CFG or step back to 90 if results look over-crisp. Hands still need the usual care; two-person prompts often collapse to one subject. Illustrious-family only.
