Details
This function "fixes" the color yellow, which by default appears green especially when darkened. The effect of this function is to make yellows appear more red, which appears more visibly yellow even when the color is darkened.
This function is intended to be tolerant to missing values. For example if
any of the values col
, Hrange
, or Hshift
are length 0, the original
col
is returned unchanged.
Value
returns a vector of R colors the same length as input col
.
In the event col
, Hrange
, or Hshift
have length 0, or if any
step in the conversion produces length 0, then the
original col
is returned.
