What is Background Color?

A first-party Runflow workflow that swaps the background of a photo for a flat color you specify via RGB channel values.

How much does Background Color cost on Runflow?

Simple fixed pricing: $0.12 per image.

How do I specify the color?

Send three integers (color_red, color_green, color_blue), each 0–255. Standard RGB.

Can I control the gradient/shading?

Shading is fixed at 30% (a soft falloff that looks photographic). For full control, pair with our Background Separation model and composite client-side.

Can I use Background Color commercially?

Yes. Commercial license; you retain ownership of inputs and outputs.

Do I need to manage GPUs or infrastructure?

No. Runflow handles all compute, queueing, and retries.
