NaPoWriMo: Day 19

I've been wanting to do a redaction poem since NaPoWriMo began, so today I'm finally doing one!

I took a paragraph of the Wikipedia article for "brown."

In terms of the visible spectrum, "brown" refers to high wavelength (low frequency) hues, yellow, orange, or red, in combination with low luminance or saturation.^[14] Since brownmay cover a wide range of the visible spectrum, composite adjectives are used such as red brown, yellowish brown, dark brown or light brown.

As a color of low intensity, brown is a tertiary color: a mix of the three subtractive primary colors is brown if the cyan content is low. Brown exists as a color perception only in the presence of a brighter color contrast.^[15] Yellow, orange, red, or rose objects are still perceived as such if the general illumination level is low, despite reflecting the same amount of red or orange light as a brown object would in normal

[the adjectives are only perceived as normal]
