All Apple CMEs and Windows Adobe ACE retained color integrity to better than delta E of 0.02. Update I have analyzed 16 bit tif conversions. For instance the Microsoft ICM, which is particularly bad, has 87% of the 16M colors undergo less than 2.0 delta E errors hence 13% exceed delta E of 2.0. To interpret the chart, look at the CME under use. The following is a cumulative deltaE error chart for each of the two CME's in Photoshop platforms. With the assistance of I have been able to compare conversions of Photoshop on Apple iOS as well as Windows for 8 bit tif images. A delta E of 1 is considered the threshold of visual color difference so this is pretty far off.Ĭonversions used Relative Colorimetric for all conversions. After the roundtrip it turned into sRGB(32,54,14) which visually, differ visually by a delta E of 12. The largest visual error occurred with the color sRGB(0,54,0). Microsoft's ICM produced significant errors mostly associated with the green channel.
