Example variety of "yellow" phenotypic appearances. When describing color, annotators tend to use soft, qualitative semantics, e.g. "yellow"; however, these contain significant semantic heterogeneity, as can be seen in the examples of (a) a yellowish corn leaf, (b) a yellow versus green corn tassel (courtesy of MaizeGDB), (c) a yellow corn cob, (d) yellow kernels, (e) a yellowish Arabidopsis leaf (courtesy of TAIR), and (f) yellow tomatoes (courtesy of SGN).
