As discussed in {{harvtxt|Sándor|Schanda|2005}}, {{harvtxt|CIE|1999}} recommends the use of a [[ColorChecker]] chart owing to the obsolescence of the original samples, of which only [[Metamerism (color)|metameric]] matches remain.<ref>[http://www.xrite.com/product_overview.aspx?ID=820&Action=Library X-Rite ColorChecker Chart].</ref> In addition to the eight ColorChart samples, two skin tone samples are defined (TCS09<sup>*</sup> and TCS10<sup>*</sup>). Accordingly, the updated general CRI is averaged over ten samples, not eight as before. Nevertheless, {{harvtxt|Hung|2002}} has determined that the patches in {{harvtxt|CIE|1995}} give better correlations for any color difference than the ColorChecker chart, whose samples are not equally distributed in a uniform color space.
