WhiteWall supports files with embedded color profiles like sRGB, AdobeRGB, and recommends using profiled files and soft proofing on calibrated monitors for best results.
Generally, we recommend profiled files for optimal results; in doubt, we recommend to soft proof your file on a calibrated monitor display or matching device.
If your uploaded files already have embedded color profiles (e.g., sRGB, AdobeRGB, eciRGB, etc.), they will, of course, be supported by WhiteWall.
