Sometimes plain old milk is a little boring. This LoRA lets you blast out different colors. It'll sometimes even do different emergent concepts like honey/beer/glowing. It's a little less flexible than I'd like due to low training data, so hopefully more can be made in the future.
To use, a weight of 0.5-1.3 worked well for me. The trigger word is "cl4ct4t10n", then use "_COLOR_ lactation" to get what you're looking for. You can add multiple colors (as separate terms, ex: "green lactation, yellow lactation" gets a swampy green) to mix them together.
