SMPTE 240M's gamut is wider than that of the BT.709 gamut and the same as BT.470 NTSC (System B, G). However, with the release of Photoshop 5.0 nearing, Adobe made the decision to include the profile within the software. </p><p>Although users loved the wider range of reproducible colors, those familiar with the SMPTE 240M specifications contacted Adobe, informing the company that it had copied the values that described idealized primaries, not actual standard ones (in a special annex to the standard).<sup class="noprint Inline-Template" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Verifiability" title="Wikipedia:Verifiability"><span title="The material near this tag failed verification of its source citation(s).

The sRGB gamut is lacking in cyan-green hues.</figcaption></figure> <p><a href="/wiki/SRGB" title="SRGB">sRGB</a> is an RGB color space proposed by <a href="/wiki/Hewlett-Packard" title="Hewlett-Packard">HP</a> and <a href="/wiki/Microsoft" title="Microsoft">Microsoft</a> in 1996 to approximate the color gamut of the (then) most common computer display devices (CRTs). Since sRGB serves as a "best guess" metric for how another person's monitor produces color, it has become the standard color space for displaying images on the Internet. sRGB's color gamut encompasses just 35% of the visible colors specified by CIE, whereas Adobe RGB (1998) encompasses slightly more than 50% of all visible colors. Adobe RGB (1998) extends into richer <a href="/wiki/Cyan" title="Cyan">cyans</a> and greens than does sRGB – for all levels of luminance. The two gamuts are often compared in mid-tone values (~50% luminance), but clear differences are evident in <a href="/wiki/Exposure_(photography)#Blacks" title="Exposure (photography)">shadows</a> (~25% luminance) and <a href="/wiki/Exposure_(photography)#Highlights" title="Exposure (photography)">highlights</a> (~75% luminance) as well. In fact, Adobe RGB (1998) expands its advantages to areas of intense orange, yellow, and <a href="/wiki/Magenta" title="Magenta">magenta</a> regions.<sup id="cite_ref-sRGBVsAdobeRGB_6-0" class="reference"><a href="#cite_note-sRGBVsAdobeRGB-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p><p>Although there is a significant difference between gamut ranges in the CIE <i>xy</i> chromaticity diagram, if the coordinates were to be transformed to fit on the <a href="/wiki/CIELUV" title="CIELUV">CIE <i>u′v′</i> chromaticity diagram</a>, which illustrates the eye's perceived variance in hue more closely, the difference in the green region is far less exaggerated. Also, although Adobe RGB (1998) can <i>theoretically</i> represent a wider gamut of colors, the color space requires special software and a complex workflow in order to utilize its full range. Otherwise, the produced colors would be squeezed into a smaller range (making them appear duller) in order to match sRGB's more widely used gamut. </p> <div class="mw-heading mw-heading3"><h3 id="Bit_depth_distribution">Bit depth distribution</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Adobe_RGB_color_space&action=edit&section=7" title="Edit section: Bit depth distribution"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Although the Adobe RGB (1998) working space clearly provides more colors to utilize, another factor to consider when choosing between color spaces is how each space influences the distribution of the image's <a href="/wiki/Color_depth" title="Color depth">bit depth</a>. Color spaces with larger gamuts "stretch" the bits over a broader region of colors, whereas smaller gamuts concentrate these <a href="/wiki/Bit" title="Bit">bits</a> within a narrow region. </p><p>A similar, yet not as dramatic concentration of bit depth occurs with Adobe RGB (1998) versus sRGB, except in three dimensions rather than one. The Adobe RGB (1998) color space occupies roughly 40% more volume than the sRGB color space, which concludes that one would only be exploiting 70% of the available bit depth if the colors in Adobe RGB (1998) are unnecessary.<sup id="cite_ref-sRGBVsAdobeRGB_6-1" class="reference"><a href="#cite_note-sRGBVsAdobeRGB-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> On the contrary, one may have plenty of "spare" bits if using a <a href="/wiki/16-bit_color" class="mw-redirect" title="16-bit color">16-bit</a> image, thus negating any reduction due to the choice of
