When you want to change or preserve a product color in Dreem, the best approach is to give a clear color reference, use a focused prompt, and check the final output objectively if the color looks different on your screen.
Dreem works best with HEX and RGB color values for color change requests. These formats give the system a clearer reference than general color names such as “beige,” “navy,” or “off-white.”
Use HEX or RGB color values
For the most precise color guidance, include a HEX or RGB value in your prompt.
Examples:
HEX:
#D8C3A5RGB:
RGB(216, 195, 165)
If you are working from a Pantone code or another color system, convert it into HEX or RGB before adding it to your prompt.
Keep your prompt focused
For color change requests, a simple and direct prompt usually works best. If you include too many instructions about the background, lighting, styling, pose, or scene, the output may introduce more visual variation.
A focused prompt might look like this:
"Change the product color to #D8C3A5. Keep the product shape, material, model, pose, and background the same."
If there are colors you want to avoid, include that too:
"Change the product color to deep navy. Do not make it black, grey, or overly saturated."
Be specific about what should stay the same
When changing only the color, tell Dreem which parts of the image should not change. This helps keep the edit focused.
Example:
"Change only the product color to RGB(216, 195, 165). Do not change the product shape, texture, model, pose, lighting, or background."
This is especially useful when the image already looks good, and you only need to adjust the product color.
Use a clear input image
If the original product image has strong shadows, reflections, poor lighting, or a busy background, the color may be harder to preserve or adjust cleanly.
For best results, use an image where the product is:
Clear and easy to see
Well-lit
Not heavily shadowed
Not affected by strong color reflections
Separated clearly from the background
Not hidden or partially covered
A cleaner input image gives Dreem a better reference for the product and its material.
Add negative guidance when needed
Negative guidance helps Dreem understand what the color should not become.
Examples:
"Do not make the product yellow."
"Keep the color deep navy, not black."
This can be helpful when a color is close to another shade or when the output keeps shifting in a direction you do not want.
Check color differences with a color picker
Sometimes a color may look different depending on the device or screen you are using. Screen resolution, display quality, brightness, and color settings can all affect how a color appears.
If the generated color looks different from what you expected, check it with a color picker. This helps confirm whether the actual color value is correct or whether the difference is caused by how the image appears on your display.
For the most reliable comparison, check the same image on the same device and display settings whenever possible.
Generate variations if you need options
If you need the closest possible visual result, generate a few variations and compare them. Some differences may appear because of lighting, shadows, material, background, or scene context.
When comparing results, use the same screen where possible and use a color picker if you need to verify the actual color value.
Recommended workflow
For the best color change results:
Use a clear, high-quality product image.
Provide the target color as HEX or RGB.
Keep the prompt focused on the color change.
Specify what should stay the same.
Add negative guidance for colors you want to avoid.
Use a color picker to verify the result if it looks different on screen.
Generate multiple variations if you need to compare options.
Following these steps helps Dreem apply your color change request more accurately and makes it easier to confirm whether the final output matches your intended color.
