Automatically Change Color Of Specific Word In MTEXT
To get you started:
If 'mtdata' is the entity data list of an Mtext object, and you want to change the string "TEST" to be red, this does that [minimally tested]:
(entmod
(subst
(cons 1 (vl-string-subst "{\\C1;TEST}" "TEST" (cdr (assoc 1 mtdata))))
(assoc 1 mtdata)
mtdata
)
)
Case-sensitive. If the word "TEST" occurs more than once in the Mtext, it will change the color of only the first instance.
It would surely be made more complicated if any other kind of Mtext-internal formatting covers that part of the content.

Make a piece of Mtext containing "TEST" in it somewhere.
Put this in at the command line:
(setq mtdata (entget (car (entsel))))
and pick that Mtext object.
Then paste in the code in my previous Reply. Change the 1 that immediately follows a C to whatever color number you prefer.
Or replace TEST in two places with WHATEVER STRING YOU WANT TO CHANGE THE COLOR OF.

That's great if the text is < (or maybe <=) 256 characters.

I doubt very much that any of their "only 8 words/phrases that I want to change to a specific color" would be of excessive length. If done that way, it would be best to put the string into a variable and (strcat) the color-coding part around it, rather than include it all twice as with the word "TEST" in my suggestion.
I forewarned about that -- see the end of Message 3. This kind of nesting colors, in an Mtext object whose overall color is white [ByLayer]:
comes to this:
(1 . "WHITE WITH {\\C1;RED INSIDE AND \\C3;GREEN INSIDE THAT\\C1; BACK TO RED} BACK TO WHITE.")
That's without both color changes starting at the same place. It doesn't merely end the green to go back to red, but instead overtly switches to red, but it merely ends the red to go back to white.
If a word is made red and then made green starting from the same place:
[that is, I picked everything that's not white and turned it all red, then picked the part that I made green inside that], it does this:
(1 . "WHITE WITH {\\C3;GREEN-INSIDE-RED\\C1; BACK TO RED} BACK TO WHITE")
in which the green overrules the original switch to red [there aren't both red and green color codes together], but then it knows to switch to it to red at the end of the green.
I gave it shot. the color did not change. I'm sure it's user error on my end.
I tried "TEST" in MTEXT.
That has a color-5 override for that text content. Is that before or after applying the original code? It looks like before, since it's just the result of setting the entity data into the mtdata variable, which should then be followed by the color-change code. If after, was it already color 5? Does it change if you REGENerate?
