Random colors via JSON API in Segment object like "col":["r","r","r"]

[AlexeyMal]

Dear Developers,

could you please add the option to set Random colors via JSON API in Segment object like col:["r","r","r"]?
As an alternative to setting the colors to the fix values.
Similar to the already impleneted "r" for palette pal and effect fx.

Why? Many people scoll through all effects and palettes using a playlist with one random effect and palette. But some effects use the 1 to 3 colors instead of the palette, so for them the colors can not be set randomly.

Thank you very much!
Best regards

wled-presets.json example:
{
"9":{"playlist":{"ps":[12],"dur":[600],"transition":[30],"repeat":0,"r":false,"end":0},"on":true,"n":"AllRandomPlaylist"},

"12":{"bri":255,"mainseg":0,"on":true,"seg":[{"bri":255,"c1":128,"c2":128,"c3":16,"cct":127,"col":["r",[0,0,0], "r"],"frz":false,"fx":"r","grp":1,"id":0,"ix":128,"m12":1,"mi":false,"o1":false,"o2":false,"o3":false,"of":0,"on":true,"pal":"r","rev":false,"sel":true,"set":0,"si":0,"spc":0,"start":0,"stop":50,"sx":128 ,"fxdef":true}],"transition":7,"n":"random effect"}
}
