I say effectively, because I guess it could look like red & white, or blue & white, but it would only be 1 color. And for all I know, what looks like gray to me may look like red to you.Watcherhttps://www.blogger.com/profile/02248341788957416471noreply@blogger.comtag:blogger.com,1999:blog-9199848742267562587.post-17570599326169216202010-02-12T13:31:44.236-07:002010-02-12T13:31:44.236-07:00WTWWU, well, I'm stumped on something, but per...WTWWU, well, I'm stumped on something, but perhaps this is more of a physics question than a biology question. If you could only see in one color, like if you could only use your red receptor cells, do you actually see in black and white? In Photoshop, clicking on only one of the RGB bands ("channels") results in a grayscale image - albeit brighter in the selected band. <br /><br />This suggests that a single band only shows you the intensity, while only two or more bands are needed to see color. I haven't yet found the answer to this question, and wonder if you've thought about it?

Yes, the Cone cells/...Snowgecko- Glad you liked it. Yes, the Cone cells/human eye graphic is mine, and you’re welcome to use it. Thanks for asking.<br /><br />As a rule of thumb, anybody is welcome to use any of my graphics. When doing so, I’d appreciate it if you could give credit to <a href="http://www.watchingtheworldwakeup.blogspot.com/" rel="nofollow">WTWWU</a>. But if you don’t, or forget or whatever, no worries. I won’t sue you or send you nasty-grams or anything.

Did you create the "Cone Cells in Human Eye" figure? May I use it?Lenahttps://www.blogger.com/profile/09698270777846656202noreply@blogger.comtag:blogger.com,1999:blog-9199848742267562587.post-26074775285510187042009-11-23T17:12:37.787-07:002009-11-23T17:12:37.787-07:00Thanks ,mountain bike riding and science .

I managed to find the article following your comment, <A HREF="http://www.csulb.edu/labs/bcl/elab/avian%20vision_intro.pdf" REL="nofollow">here</A>.<BR/><BR/>I wish I'd found this when I was researching the post; it's got great additional info (specially about UV vision in birds) and is very readable.

One cool thing they noted is that some of the birds (like starlings) that we see as drab, with no difference between males and females, are much different in the wavelengths that the birds themselves see. If we saw the way starlings do, male starlings would be bright and gaudy. For some reason, I really like knowing that.Mark Vande Kamphttps://www.blogger.com/profile/14839049554383052515noreply@blogger.comtag:blogger.com,1999:blog-9199848742267562587.post-80414774540571775852008-11-27T20:40:00.000-07:002008-11-27T20:40:00.000-07:00All right, this blog rocks.
