ComfyUI Try it →Watch full video →Urban Decoders · Aug 2025

Demo summary

The video shows how to use a reference image to transform a realistic house photo into a watercolor painting style using Flux Kontext.

Step-by-step

Load the original image you want to transform into the ComfyUI workflow
Upload a reference image that represents the target style, such as a watercolor painting
Enter a prompt describing the desired changes while specifying elements to keep, like architectural forms
Run the generation to apply the style transfer

Options

Transform images into various styles such as sketches or watercolors

Tips

Use reference images that you specifically like to iterate through different styles quickly
Include instructions in your prompt to keep the camera angle and architecture consistent

Highlights

“This is a very quick way to iterate through different styles, especially if you have reference images that you like.”
