Here is a pic of a girlscout, your "kato", a cubscout and Chris' Kato.
You say it has both green and blue in them.....Well I see it in Chris'
maybe the green is under the blue on hers and on yours..... the blue must be under the green???? because it looks like a girlscout to me.
Chris' is definately a Kato.
it is turquiose.
I'm sure there must be variations.
