Determine if colors are blank colors
isColorBlank(
x,
c_max = 7,
l_min = 95,
alpha_max = 0.1,
blankColor = c("#FFFFFF", "#FFFFFFFF", "transparent"),
...
)character vector of R colors.
maximum chroma as determined by HCL color space, in range of no color 0 to maximum color 100.
numeric minimum luminance required for a color to be
considered blank, combined with the c_max argument. This
threshold prevents grey colors from being considered blank,
unless their luminance is above this threshold.
numeric value indicating the alpha transparency below which a color is considered blank, in range of fully transparent 0, to fully non-transparent 1.
character vector of R colors directly matched to
the input x vector. The value "transparent" is useful here,
because it is not easily converted to HCL color space.
additional arguments are ignored.
This function takes a vector of colors and determines if each color
is considered a "blank color", based upon direct match and the
color chroma saturation and luminance. For example, extremely pale
colors from colorjam::vals2colorLevels() may be considered "blank" if the
color saturation is extremely low. Similarly, colors with
extremely high alpha transparency may be considered "blank".
