retinal_echo, prism_offset, negative_afterimage, complementary_color_echo, color_shadow_echo, displaced_silhouette, spectral_offset, retinal_ghost, echo_trail, A retinal echo style image of a single large multicolored feather, shown as the clear central subject in a diagonal composition. The feather has vivid rainbow tones including cyan, turquoise, magenta, pink, yellow, orange, and deep blue, with fine soft barbs and a sharply readable central shaft. Clean prism offset contour layers and complementary negative afterimage echoes appear along both sides of the feather, creating crisp displaced silhouette duplicates with strong optical residue. The main feather remains clearly readable while the echo layers add controlled visual separation. Set it against a simple soft teal-to-light aqua painterly background with subtle texture and no distracting elements. <lora:zit_ta86_yal_retinal_echo_light:0.7>
