30    of the channel values, which means the image appearance will change (unless
31    the original and new profile are functionally equivalent).</para></note>

59    <orderedlist>
60      <listitem>
61        <para>
62          The image's <emphasis>appearance</emphasis> will change
63          (unless the image is already in an ICC profile color space that has the
64          same colorants and channel encoding as the newly-assigned GIMP sRGB
65          color space).

68      <listitem>
69        <para>
70          The image's <emphasis>channel values</emphasis> are not
71          changed by discarding the currently assigned profile and instead assigning
72          GIMP's built-in sRGB profile.

74      </listitem>

77    <para>
78      Discarding the image's currently assigned profile is useful if
79      you wish to export an image to disk without an embedded ICC profile.
80    </para>
81
82    <para>
83      <guimenuitem>Discard Color Profile</guimenuitem> can only be used
84      if the ICC color profile assigned to the image is not a GIMP built-in
85      sRGB profile. GIMP's built-in sRGB profiles are not embedded in images
86      that are exported to disk.
