Coloring a Font with a RGB etc. without adding the color to the document swatches.

Question

Is there a way of coloring a font with a RGB, Lab or CMYK color without adding the color to the document swatches.
The only way I know is to add a color to the swatches or use one that already exists.
like
   app.selection[0].characters[0].fillColor=document.colors.add({colorValue: [255, 53, 160], space: ColorSpace.RGB});}
This has the undesired effect of cluttering up the swatches when using a lot of colors.
any ideas?

Good Morning Uwe!
After 3am by me 2am by you
I had tried the link and it did download but I have cs5 cs6 and cc but not cs5.5 and all the scripts worked on them may because of the file conversion.
So it looks like the following summary is all correct
All documents new contain
Swatches (Black, Registration, Paper and None) the index order will be the order that the swatches appear in the swatches panel
And colors in an alphabetical index order
named color "A" first "Z" last and then the unnamed colors.
A such all new documents colors[-1] will be an unnamed color which we can duplicated to produce other unnamed colors taking note that the duplication must be process and not spot colors.
So far so good, (not for long )
Unnamed colors are not read only so if we make a positive effort to remove them we can do that.
while (app.activeDocument.colors[-1].name == "") app.activeDocument.colors[-1].remove()
We now won't have any unnamed swatches to duplicate and will have to resort to John's tagged text file method in 3 above.
If there were no unnamed swatches and we try to duplicate colors[-1] and it was a color like "Yellow" then it seem's to crash indesign.
Anyway the below method should always work (for regular non tint etc. type colors).
// optimized for easy of use but not efficiency !!!
var doc = app.documents.add();
var p = doc.pages[0];
p.textFrames.add({contents: "RGB", geometricBounds: ["0mm", "0mm", "30mm", "30mm"], fillColor: addUnnamedColor([0, 0,255])}); // will be a RGB
p.textFrames.add({contents: "RGB", geometricBounds: ["0mm", "30mm", "30mm", "60mm"], fillColor: addUnnamedColor([0, 255,0], 1666336578)}); // will be a RGB because of value
p.textFrames.add({contents: "RGB", geometricBounds: ["0mm", "60mm", "30mm", "90mm"], fillColor: addUnnamedColor([65, 50, 102], ColorSpace.RGB)}); // will be a RGB
p.textFrames.add({contents: "RGB", geometricBounds: ["0mm", "90mm", "30mm", "120mm"], fillColor: addUnnamedColor([84, 90,40],"r")}); // will be a RGB
p.textFrames.add({contents: "RGB", geometricBounds: ["0mm", "120mm", "30mm", "150mm"], fillColor: addUnnamedColor([232, 0, 128],1)}); // will be a RGB
p.textFrames.add({contents: "Lab", geometricBounds: ["30mm", "0mm", "60mm", "30mm"], fillColor: addUnnamedColor([29.5, 67.5, -112])}); // will be a Lab because of -
p.textFrames.add({contents: "Lab", geometricBounds: ["30mm", "30mm", "60mm", "60mm"], fillColor: addUnnamedColor([100, -128, 127], 1665941826)}); // will be a Lab because of value
p.textFrames.add({contents: "Lab", geometricBounds: ["30mm", "60mm", "60mm", "90mm"], fillColor: addUnnamedColor([24.5, 16, -29], ColorSpace.LAB)}); // will be a Lab
p.textFrames.add({contents: "Lab", geometricBounds: ["30mm", "90mm", "60mm", "120mm"], fillColor: addUnnamedColor([36.8, -9, 27],"l")}); // will be a Lab
p.textFrames.add({contents: "Lab", geometricBounds: ["30mm", "120mm", "60mm", "150mm"], fillColor: addUnnamedColor([51, 78, 0], -1)}); // will be a Lab because of the 1
p.textFrames.add({contents: "CMYK", geometricBounds: ["60mm", "0mm", "90mm", "30mm"], fillColor: addUnnamedColor([82, 72, 0, 0])}); // will be a CMYK because there are 4 color values
p.textFrames.add({contents: "CMYK", geometricBounds: ["60mm", "30mm", "90mm", "60mm"], fillColor: addUnnamedColor([60, 0, 100, 0], 1129142603)}); // will be a CMYK because of value
p.textFrames.add({contents: "CMYK", geometricBounds: ["60mm", "60mm", "90mm", "90mm"], fillColor: addUnnamedColor([84, 90,40, 0], ColorSpace.CMYK)}); // will be a CMYK
p.textFrames.add({contents: "CMYK", geometricBounds: ["60mm", "90mm", "90mm", "120mm"], fillColor: addUnnamedColor([67, 53, 97.6, 21.7], "c")}); // will be a CMYK
p.textFrames.add({contents: "CMYK", geometricBounds: ["60mm", "120mm", "90mm", "150mm"], fillColor: addUnnamedColor([0, 100, 0, 0], 0)}); // will be a CMYK
function addUnnamedColor (cValue, space, docToAddColor) {
    docToAddColor = app.documents.length && (docToAddColor || (app.properties.activeDocument && app.activeDocument) || app.documents[0]);
    if (!docToAddColor) return;
    var lastColor = docToAddColor.colors[-1];
    if (!cValue) cValue = [0,0,0,0];
    if (space == 1129142603 || cValue && cValue.length == 4) space = ColorSpace.CMYK;
    else if ((space && space < 0) ||  space && space == 1665941826 || (space && /L|-/i.test(space.toString())) || (cValue && /-/.test(cValue ))) space = ColorSpace.LAB;
    else if ((space && space > 0) || space && space == 1666336578 || (space && /R/i.test(space.toString())) || (cValue && cValue.length == 3)) space = ColorSpace.RGB;
    else space = ColorSpace.CMYK;
    app.doScript (
        var newUnnamedColor = (lastColor.name == "") ? lastColor.duplicate() : taggedColor();
        newUnnamedColor.properties = {space: space, colorValue: cValue};
        ScriptLanguage.javascript,
        undefined,
        UndoModes.FAST_ENTIRE_SCRIPT
     function taggedColor() { // need to use this if no unnamed exists
             var tagString = "<ASCII-" + ($.os[0] == "M" ? "MAC>\r " : "WIN>\r ") + "<cColor:COLOR\:CMYK\:Process\:0.1\,0.95\,0.3\,0.0><cColor:>"; // would make more sense to apply the correct value in the tagged text file but I can't be bothered !
             var tempFile = new File (Folder (Folder.temp) + "/ " + (new Date).getTime() + ".txt");
             tempFile.open('w');
             tempFile.write(tagString);
             tempFile.close();
             var tempFrame = docToAddColor.pages[-1].textFrames.add();
             $.sleep(250);
             tempFrame.place(tempFile);
             tempFrame.remove();
             tempFile.remove();
         return docToAddColor.colors[-1];
    return newUnnamedColor;
Shall apply the function to delete and replace swatch on the other thread at a more sane time
