> [@](#): > > \*Originally posted by Broomstick \* > **Gee, I dunno, Chorpler, did it blast past you that I don’t need to do anything special to see the 2 - that’s _all I see?_** Overreact much? Talk about a _post hoc_ reaction. Nowhere did **chorpler** even remotely suggest he was referring to your post and if you can demonstrate differently, I will eat my own left arm. Christ, just because someone posts after you do does NOT mean they are posting in answer to you. Get a grip already. I respect you for the most part, but too often you take personal offense to things that, quite frankly, have exactly squat to do with you. ---

Chill, dude - yes, I am not only posting after you, I am also talking to you. Like everyone else out here, I sometimes try to pull someone’s leg a little and don’t always pull it off with grace. And I’ll decide what does and doesn’t have something to do with me, thank you very much. ---

I knew there was a reason I liked you, Q.E.D. … 😉 Also, Broomstick, while I indeed wasn’t referring to your post, I _would_ be interested to know if you can see the 5 when you try your idea of greatly increasing the green on your display. ---

Ah. Humor. Humor is funny. Anyhow, [here](http://www.gitchat.org/Color5-2G.jpg) is the color plate with the green level cranked up (very yellow–ick). Can you see the 5 now, **Broomstick**? I wasn’t sure what level was sufficient, so I dialled it up about halfway. ---

Can you see the 5 now, **Broomstick**? I wasn’t sure what level was sufficient, so I dialled it up about halfway. Ew, yuck, not a color I’d pick to paint my walls, for sure. But yes, I can now faintly see a sort of white and faintly green five superimposed over a much more distinct two, where before I couldn’t see a five _at all_.
