The Geckos That Trade Colors

A terrarium houses 4545 geckos: 1313 amber, 1515 teal, and 1717 crimson. Whenever two geckos of different colors meet, both instantly switch to the third color — an amber and a teal meeting both turn crimson, and so on. Meetings can be arranged in any order you like. Is there a sequence of meetings after which all 4545 geckos share a single color?
