Key Takeaways
- Milk bath (
milk bath) was consistently reproduced across all 6 conditions. The white, opaque liquid filling a bathtub was rendered with very high reliability rose petals floatingaccurately places rose petals on the water surface. The number and arrangement of petals look natural, producing the most elegant resultstrawberry milk bath, pink milky waterproduces a pink-tinted strawberry milk bath. Actual strawberries also appear floating on the surface, making it an effective color variationmilk poured over headproduces a milk shower scene. The composition shifts entirely from bathing to a standing studio shot – a completely different genrematcha milk bath, green milky waterproduces a matcha milk bath. However, the opacity is lower than a standard milk bath, with the greenish water appearing somewhat translucentcoconut milk bath, tropical flowers floatingproduces a tropical coconut milk bath. Coconuts and plumeria flowers float on the surface, creating a resort spa atmosphere
Experiment Design
| Parameter | Value |
|---|---|
| Model | z-image-turbo (6B, photorealistic distilled model) |
| Steps | 8 |
| CFG | 1.0 |
| Image Size | 1024x1024 |
| Seed | Fixed per condition (42–47) |
| Variable | Milk bath variation description only (1 variable) |
One image was generated per condition. Since previous testing in the WAM guide confirmed high reproducibility for milk bath, this experiment prioritized breadth of variation over per-condition sample size.
Experiment 1: Rose Petal Milk Bath (Control)

Observations
White, milky water fills the bathtub with pink rose petals scattered across the surface. More than 10 petals are visible, with natural sizing. Shoulders and above are visible above the waterline, and body coverage is naturally achieved by the milk’s opacity. A tiled bathroom is rendered in the background, accurately reflecting the indoor bathroom specification. The overall color tone is calm and the atmosphere is elegant.
Experiment 2: Strawberry Milk Bath

Observations
The water color shifted to a pinkish milky white. pink milky water is accurately reflected. Multiple strawberries float on the surface – the strawberry milk bath prompt generated the fruit itself. Rose petals are interspersed among the strawberries. Compared to Condition 0, the colors are more vibrant and photogenic. The bathroom setting is maintained.
Experiment 3: Milk Shower

Observations
This is the only condition that produced a standing studio shot rather than a bathing scene. The subject wears a white bikini with milk being poured from above, flowing down through hair and body. Both milk poured over head and milk dripping from hair and body are reflected. A gray plain background with studio lighting is rendered – an entirely different genre from the other conditions. The liquid rendering of the milk (flow and droplets) appears natural.
Experiment 4: Matcha Milk Bath

Observations
The water turned green, reflecting the green milky water specification. However, compared to the standard milk bath (Condition 0), the opacity is lower, with the body slightly visible beneath the surface. There is a texture suggesting matcha powder floating on the water surface, resembling an actual matcha bath. The bathtub is a classic clawfoot design, different from Condition 0.
Experiment 5: Extra Petals Milk Bath

Observations
Compared to the rose petal milk bath in Condition 0, the quantity of flowers increased significantly. many flower petals floating is working effectively. Purple lavender flowers and pink/orange roses cover the water surface, with the flower types accurately separated as specified by lavender and rose petals. candles placed candles around the bathtub, and warm lighting produced warm-toned lighting. This is the most decorative and luxurious result.
Experiment 6: Coconut Milk Bath

Observations
White milky water with two coconuts and numerous plumeria flowers floating on the surface. Similar to the strawberry milk bath, coconut milk bath generated the actual coconuts. The outdoor bath specification produced a stone bathtub in an outdoor setting, and tropical flowers floating rendered plumeria (frangipani) in red, white, and yellow. The overall atmosphere resembles a resort spa.
Summary
| Condition | Water Color | Floating Objects | Composition | Characteristics |
|---|---|---|---|---|
| Rose Petal Milk Bath | White (milky) | Rose petals | Bathtub | Most orthodox and elegant |
| Strawberry Milk Bath | Pink | Strawberries + petals | Bathtub | Vibrant and photogenic |
| Milk Shower | – | – | Studio standing | Different genre entirely |
| Matcha Milk Bath | Green | Matcha powder | Bathtub | Lower opacity |
| Extra Petals Milk Bath | White (milky) | Lavender + roses + candles | Bathtub | Most decorative and luxurious |
| Coconut Milk Bath | White (milky) | Coconuts + plumeria | Outdoor stone bath | Strong resort feel |
The milk bath concept has very high reproducibility with the milk bath prompt, and color and floating object variations are faithfully reflected. For elegant bathing scenes, the rose petal milk bath (Condition 0) or extra petals (Condition 4) work best. For color impact, try strawberry milk (Condition 1). For a resort atmosphere, coconut milk (Condition 5) is the way to go.
