Blends two colors in the proportion specified by the float parameter.

BLEND(color1,color2,float[0,1])

Parameters

Name

Required/Optional

Data Type

Description

color1

Required

Numeric

The Visio color index or RGB value of the first color.

color2

Required

Numeric

The Visio color index or RGB value of the second color.

float[0,1]

Required

Float

The proportion in which to blend color2 and color1, respectively. A real number from 0 to 1 inclusive.

Return Value

RGB

The color returned is determined by the relative proportions in which to blend color2 and color1, respectively, as specified by the float parameter. For example, if float is 0.25, the color returned is composed 75% of color1 and 25% of color2.

Another way to think about it is that the float value corresponds to the point along the color spectrum from color1 to color2. Therefore, smaller numbers (closer to zero) for float produce blends closer to color1, while larger numbers (closer to 1) produce blends closer to color2.
