You may have your recolors included in the Sims2Pack. After creating the Sims2Pack file, open it, uncheck the recolors you don't want to include, click Update, then save as a new file. You can remove unwanted sims and mods this way, too, if you're packaging a lot.
Then compress the file into either .rar or .zip format and you're set to upload.
It`s worth to remember. Getting wiser every day :-P. Thanks a lot Ancienthighway
