Colors in Matlab
RGB colors
For coding purposes colors are mostly specified in RGB, which stands for Red, Blue and Green. The values range from 0 to 1. As an example: the color red is given by the triple [1,0,0]. Since it is hard to know what a certain triple (e.g. [0.5, 1, 0.5]) stands for it is more easy to call them by their name.
We have created a few functions for RGB colors by their names:
- <RGBcolors> for english names
- <RGBkleuren> for dutch names
- <RGBfarben> for german names
- <RGBcolores> for spanish names
A few examples:
>>colores.AZUL_CLARO ans = 0.5000 0.5000 1.0000 >>kleuren.FELROZE ans = 0.5000 0.5000 1.0000 >>farben.BLAU ans = 0.0000 0.0000 1.0000 >>colors.LIME ans = 0.0000 1.0000 0.0000
All the named colors are:

Color maps
You can make a color map for plots like surface plots:
map = [RGBcolors.LIME, RGBcolors.BLUE, RGBcolors.MAGENTA]; colormap(map); surf(peaks);
| Name | Description |
|---|---|
| parula | A smooth, perceptually uniform colormap with blue-to-yellow transitions, default in MATLAB since version R2014b. |
| turbo | A vibrant, perceptually uniform colormap with a wide dynamic range, transitioning from blue to red via green and yellow. |
| hsv | A circular colormap representing the hue component in the HSV color space, cycling through the full range of colors. |
| hot | A colormap with transitions from black to red, then yellow, and finally white, typically used for thermal or intensity data. |
| cool | A simple linear colormap that transitions smoothly from cyan to magenta, often used for contrast with warm color schemes. |
| spring | A pastel colormap transitioning from magenta to yellow, often used to represent seasonal or thematic data. |
| summer | A light green to yellow colormap that gives a warm, sunny feel, used for representing continuous data. |
| autumn | A colormap with warm tones transitioning from red to yellow, evoking the colors of autumn leaves. |
| winter | A cool colormap transitioning from blue to green, commonly used to represent water or icy conditions. |
| gray | A simple grayscale colormap, transitioning linearly from black to white, often used in intensity maps. |
| bone | A colormap with a grayscale base, but with a slight blue tint, designed for displaying images of bones and x-rays. |
| copper | A colormap transitioning from black to copper-brown, useful for visualizing data with metallic or heat-related themes. |
| pink | A pastel colormap with a gradient from dark to light pink, often used for softer data visualizations. |
| lines | A colormap with distinct, evenly spaced colors, designed for line plots with many different lines. |
| jet | A rainbow colormap transitioning from blue to red, previously the default in MATLAB, but criticized for non-uniform perceptual changes. |
| colorcube | A discrete colormap that uses a fixed set of distinct colors, typically used for categorical or label-based data. |
| prism | A repeating sequence of vivid colors, often used for periodic or cyclic data. |
| flag | An alternating red, white, blue, and black colormap, often used for data with binary or oscillating patterns. |
