For those interested in trying out DiT workflows for coloring the reference frames, I suggest to try to install the Windos portable version of ComfyUI.
ComfyUI is a little complex to use but is very powerful and there is a lot of documentation available, see: https://docs.comfy.org/
Once you have installed ComfyUI, download the workflow for Qwen Image Edit (similar to Nano Banana but free): qwen-image-edit-2511
Once you have the workflow loaded in ComfyUI, load a B&W image that you want to colorize.
Then change the prompt include in the example with: "Colorize this black and white photo with realistic, vibrant colors while preserving skin tones. Strictly preserve all shapes, edges and background details."
I suggest ComfUI as a free alternative to Nano Banana, moreover the users more skilled could try to automatize the coloring of reference frames with ComfUI (better ask to Gemini how to do that).
Currently mi coloring pipeline is similar to the one described in the chapter "Advanced coloring using adjusted reference frames" in my user guide, the only difference is that instead to manually adjust the reference frames using Photoshop Elements, now I'm using Nunchaku Qwen-Image-Edit-2511 (available also in ComfyUI). Given the very good results obtained with this DiT model, I decided to color all the reference frames in this way, then I use ColorMNet (with Vivid unchecked) with Method "external RF different from Video" to colorize all the movie as described at the pages 50-59 of my user guide.
I recently published this movie: A Night To Remember (Colorized, 1958) that was colored using this new pipeline. Looking at this video (which can be easily downloaded) you can see that the colors are very accurate, vivid and quite stable, something that cannot be achieved using DeOldify and/or DDColor. The colors are so accurate that it looks like the movie was filmed in Color and not "colorized".
