![]() ![]() It also uses the function ISMEMBER to do the conversions. Note that this function allows you to input either a string of characters or an N-by-3 numeric or logical array (with RGB values from 0 to 1 or 0 to 255) and it returns the opposite color representation. 'Input must be a character or numeric array.') For example, you can specify a shade of pink as 1 0.5 0.8. Many plotting functions have an input argument such as c or colorspecfor customizing the color. You can customize the colors if you need to. Currently, the accompanying MATLAB script can calculate optimal RGB values for di-, tri-, and tetrachromats, but it is our intent to add functionality for. ![]() The default colors provide a clean and consistent look across the different plots you create. The intensities must be in the range 0,1. MATLAB® creates plots using a default set of colors. 'RGB input must define one of the colors ''rgbcmywk''.') RGB Triplet Create a custom color by specifying a three-element row vector whose elements are the intensities of the red, green, and blue components of a color. InColor(scaleIndex,:) = inColor(scaleIndex,:)./255 %# Scale by 255 The red, green and blue use 8 bits each, which have integer values from 0 to 255. ScaleIndex = max(inColor,2) > 1 %# Find rows with values > 1 Green: Blue: RGB color space RGB color space or RGB color system, constructs all the colors from the combination of the R ed, G reen and B lue colors. InColor = double(inColor) %# Convert input to type double 'Numeric input must be an N-by-3 matrix') In many MATLAB plotting functions, you can specify the color as either a string or as a 3 element vector that directly lists the red, green, and blue values. 'String input can only contain the characters ''rgbcmywk''.') Įlseif isnumeric(inColor) || islogical(inColor) %# Input is a numeric orĪssert(size(inColor,2) = 3,'convert_color:badInputSize'. So currently I have 'y-' but again I dont want to use yellow 0 Comments Sign in to comment. How can I make my own color I also want this line to have asterisks along it. ![]() = ismember(inColor(:),charValues) Īssert(all(isColor),'convert_color:badInputContents'. 1 Link Moved: Image Analyst on Accepted Answer: Chad Greene I have 7 lines on a single plot. If ischar(inColor) %# Input is a character string This approach allows computations of the color similarity of two given RGB colors by simply calculating the distance between them: the shorter the distance, the.

Use the below-given weblink for the datasheet for using various RGB. single characters): function outColor = convert_color(inColor) 25 2.3K views 2 years ago my Matlab videos Stunning plot colours in MATLAB RGB code for changing plot colours. If you're only concerned with conversions for the default 8 color strings, here's a function I wrote myself that I use to convert back and forth between RGB triples and short color names (i.e. I found this general alternative on the MathWorks File Exchange which will even handle color strings other than the default 8 in MATLAB: ![]()
