It defines an expanded gamut by means of encoding pixel values outside the normal range of. The scRGB color space uses the same primaries as sRGB but with a linear curve. This was done partially as an exercise to determine the minimum size for a useable sRGB-compatible profile and partially because sRGB is a special case where an extra-small profile may be useful. In addition to the usual V2 variants, I have created a -nano version of the sRGB profile. 709 primaries, which are commonly given as sRGB. The values in these profiles differ very slightly from those in profiles derived from the Rec. These profiles are defined using the true sRGB primaries, as defined in both the sRGB and scRGB standards, using the process defined in the ICC's extension spec for sRGB profile makers. These curves have been tuned so that in many cases they will give greater accuracy than the standard TRCs despite the smaller size, hence the name: magic. For more accuracy, the -magic version of the profile uses a TRC with a larger number of points while still being significantly smaller than the standard profiles that use 1024 curve points. The -micro version of the profile uses a TRC that is balanced between accuracy and size and should be more than adequate for any 8-bit per channel images (e.g. For the V2 profiles, I have created two variants: -micro and -magic.

These color spaces are best represented using the newer V4 parametric curve type, so if you know the software reading the image is V4 compatible, those are the best choice. V2 profiles can be made smaller, and V2 has better software support, but V4 allows for a slight increase in the gamma precision.įor color spaces that have complex tone reproduction curves (TRCs), I have provided multiple options.

They are free from restrictions on distribution and use to the extent allowed by law.ĭetails on the process used for creating these profiles can be found here Conventionsįor color spaces that use a constant gamma value, profiles are provided in both ICC V2 and V4 versions (with the exception of HDR video color spaces, which are V4 only). All profiles in this collection are released to the public domain under the Creative Commons CC0 license. Profile description and copyright text are minimal. These profiles are intended for embedding in image files or software where the size of the profile is a consideration. The ICC profiles in this collection contain the minimum tags necessary to correctly represent a color space and, in the case of ICC V2 profiles, use custom packing to mimimize file size.
