bmiColors1

bmiColors1 is a color palette used in data visualization to represent body mass index (BMI) data. It is typically implemented as an ordered list of color values that maps BMI figures to a gradient on charts, maps, and heatmaps. As part of a family of bmiColors palettes, bmiColors1 usually provides a sequential ramp designed to convey increasing BMI values through changing colors.

Composition and design principles commonly found in bmiColors1 include a range of 7 to 11 colors defined in hexadecimal RGB or RGBA formats. The progression typically runs from cooler tones for lower BMI values to warmer tones for higher BMI values, aiding quick visual interpretation. Some deployments offer a color-blind friendly variant that uses hues chosen for better distinguishability by readers with color vision deficiencies.

Usage and implementation considerations: In plotting libraries, bmiColors1 is supplied to color scale constructors to create the mapping between numeric BMI values and colors. Values are often normalized to a 0–1 scale before applying the palette, ensuring a consistent gradient across different datasets and display sizes. The palette may be embedded in configuration files or generated programmatically within visualization code.

Origin and context: The name bmiColors1 suggests a first version in a series of BMI-focused palettes used in data dashboards, academic projects, or reports. Exact color values and the availability of alternative variants can vary by project or software package, but the underlying concept remains a straightforward gradient-based color mapping for BMI-related visuals.
