Adobe Stock explicitly states this in their contributor guidelines.
Key Points:
sRGB is the Standard: It is the color space widely used and accepted as the standard for display on the web, mobile devices, and for most general-purpose use.
-
Consistency: Using sRGB ensures that your images will display with the correct colors and saturation across the majority of screens and viewing platforms, preventing the dull or "washed out" look that can happen when an Adobe RGB file is viewed in a non-color-managed web browser.
-
Technical Requirement: Adobe Stock lists sRGB as the required color space for photos and illustrations.
What to Avoid:
Adobe RGB: While Adobe RGB offers a wider color gamut (more colors), it's primarily used for professional-level printing workflows. Uploading Adobe RGB files to web platforms without converting them can cause the colors to appear muted or incorrect to many viewers whose monitors are only calibrated for sRGB.
-
CMYK: Images for Adobe Stock should be in the RGB color space (specifically sRGB). CMYK (Cyan, Magenta, Yellow, Key/Black) is for print production and is not compatible with web display standards.
In summary, make sure to convert or export your final image files to the sRGB color profile before submitting them to Adobe Stock.
