well randerlize your self
You turn them purple.
There is blue, red, brown, green, black, yellow, and purple (and maybe some other colors, I don't remember anymore) . But the eye color that is needed for completing Lunar Colony is purple.
Well I really don't know, but I tried all of the colors and none of them work. So I guess it's just a bug or something.
To enter the Rock lab, you need a keycard (dropped by Salerno when you find her) and purple eyes that you can get from the machine in the Research Lab.
It doesn't matter. Yours have to be purple to fool the retina scans, because you are not one of the regular astronauts -- their retina patterns are recognized by the security system at the Rock Lab.
Just as you enter the Research Lab (building north of the main base), you will see the eye-color research unit. It states that purple eyes may cause detection problems with retina scans. Change yours to purple (they will change back when you finish the quest).
The boxes are blocking the Infirmary door at the Research Lab.Go to the pressure chamber (upper left). Get in the chamber and click High Pressure. You must act quickly and move your character to the bottom left corner, to squeeze past the boxes to the door.(You should also go to the eye-color changing station. Change your eyes to purple. This will help later.)
You need purple eyes to pass the retina scan at the Rock Lab. As explained on the computer in the Research lab, it can fool the scans used for security. Change them in the Research Lab. They will change back automatically.
Cathy Codex is a purple dressed girl with a purple dress, pure pearl earrings, large purple glasses, tiny dark eyes, and slick black hair held back in a bun by a purple scrunchie. She's a contestant on Reality TV on Reality TV Island on Poptropica.
yes. if you want to change your Poptropican's eyes then you have to randomize your person. To do this press the key R while holding down keys Ctrl and shift. Warning: by doing this you will change your person's outfit. And can not be undone
Once you have found Salerno at the Biodome, follow her back to the Rock lab and use her key card to enter (you need purple eyes to beat the retina scan). Cross the processing center and reach the storage area on the far side (upper right). You will find a geiger counter, and you can use some support beams to make a ramp for it. Use the counter in the rover to find the Purple Artifact and pull away the rock covering it. At the intersection of the artifact beams is an alien base. For the full solution, see the related questions below.
You get the keycard when you follow Salerno to the BioDome. As she escapes, she drops the card by the airlock. You will chase her in the rover to the Rock lab, but you also have to have purple eyes to fool the retina scan. You get them when you are at the Research Lab (upper right by the airlock). To find Salerno, you have to get the tracking device from the Infirmary.
