/Con level question

[Ealadar]

I am curious about the consider color messages and experience given. I see a lot of posts about light blue consider and I know this is a thing on live but at level 50 all I see are blue and green consider colors. Now there are two different consider messages for green and one gives experience where the other does not. Is this a client side thing I am not seeing or are light blues actually green in color and just called light blue to differentiate the ones that give exp and the other that does not.

The second part of the question is experience given per kill. Is a light blue or green consider creature 1/2 of a blue kill? I know there is a section on this in the newbie guide but due to the colors (no light blue) I am not 100% sure of the answer.

Thanks for the help!
