Is there a color database existent?

Is there a simple color database existent containing a bunch of RGB colors which I could use in my script to create colored images?

e.g. I'd like to be able to do this

image(LG) %%-> selects LG from database which gives a light green image

Download my FEX submission colornames:

https://www.mathworks.com/matlabcentral/fileexchange/48155-convert-between-rgb-and-color-names

then simply create an array using those colors, and show that using image or imshow:

>> [~,rgb] = colornames('SVG','LightGreen');
>> A = reshape(rgb,1,1,3)
>> image(A)

Note that colornames supports many common color palettes, yet is very simple to use:

[clr,rgb] = colornames('HTML4','blue','red','teal','olive')
clr =
    'Blue'
    'Red'
    'Teal'
    'Olive'
rgb =
      0       0       1
      1       0       0
      0       0.50196 0.50196
      0.50196 0.50196 0
