Moraea ochroleuca colours and words

 Can this shade of yellow be called sallow? Such descriptor is embedded in the specific name of Moraea ochroleuca.

The observed floral colouring as well as the colour describing words vary and contain uncertainty as to the shades on show. Levels of linguistic accuracy, precision or effectiveness rarely do better than approximate the truth they attempt to tell. The functionality of available terminology or the power of words is sometimes challenged by the real-world features they try to describe.

Photos may cover for words, but then more photos may surprise by illustrating complexities missed. The truth is elusive (Marais, (Ed.), 2017; Manning, 2007; Bean and Johns, 2005; iNaturalist; https://www.fernkloof.org.za).
