Bulb Upgradingness questions

[BigBlueX]

When i turn my truck on, i have those yellow running day lights. i want them to be white or blue, like an HID. Those running daylights are also the high beams correct? I'm wondering if i get an HID kit for bi-xenon (hi/low) one bulb, if i can get HID running day lights? Also i want brighter fog lights. what is the K on the OEM xenon bulbs. What i bascially want is all the lights to be white or blue not the ugly yellow. Would it be possible to just switch the bulb from a yellow to white without having to do ballasts etc. Let me know if you need anything cleared up.

THANKS GUYS
