a slope that won't admit it's a slope, just elegant indecision between two colors.
means A gradient is the rate at which something changes over distance — a slope, an incline, or a smooth transition from one value (or color) to another.
from From Latin gradi, 'to step or walk,' and its noun gradus, 'a step' — the same root that strides through 'grade,' 'progress,' and 'degree.' English fashioned 'gradient' in the 19th century, originally for the slope of a railway or road, modeled on words like 'salient'; only later did mathematicians and designers borrow it for any steady incline of change, including the soft walk from one color to the next.
