As I shifted to where the extra-bold white writing is, I got 'opacity' along all the colour boundaries, changing a little as the visual system adjusts to movements of the card.<br /><br />In my design course they had us read (pretty sure this was the book) Johannes Itten's <i>The Art of Colour</i>, which I recall is quite big on thing slike boundary effects. Though yeah, not certain what you do with that information if you're not at the Bauhaus.Lyndonhttps://www.blogger.com/profile/05622953598107216261noreply@blogger.comtag:blogger.com,1999:blog-2999230124118604245.post-38656678884319668702011-04-07T18:44:17.762-04:002011-04-07T18:44:17.762-04:00James-

I can never see any of the bi-ocular illusions because I can only see with one eye (I do have some peripheral vision in my bad eye which helps with depth perception), but I like learning about them and how they influence other's perceptions.<br />The “watercolor illusion” effect is a fun graphic trick used in poster art, as you point out. I think both of these illusions are used by sign painters all the time (intentionally or not). The importance of edges is particularly evident when executing very large signs and graphics. Most of these projects are on very uneven surfaces, and executed by a team working very fast and very up close. After the piece is completed there is usually a final touch-up pass made over the whole image, in order to fix little mistakes or drips, or to clean up lines etc. It is always amazing to me how much of all these little errors, which are quite visible up close hanging on the wall, yet can’t be seen from just a few feet away on the ground; And the ones that are seen are usually around the perimeter, or where there are edges.<br /><br />@Scorchfield- Thanks for the trip,Man! That’s some pretty good stuff.

It looks from a distance that one is warmer overall, as if the highlights are borrowing from the more vibrant edge. I wonder if the same thing here applies to those paintings.Anthony VanArsdalehttps://www.blogger.com/profile/04239147412646328392noreply@blogger.comtag:blogger.com,1999:blog-2999230124118604245.post-83713994191335698662011-04-05T14:05:27.762-04:002011-04-05T14:05:27.762-04:00Another dimension of ilusion:

It seems one possible painting take-away from knowing the primancy our visual system confers to reading edges is that we can use warm background colors (which generally bring objects forward) and still have them seem to recede if we carefully construct our edges and negative shapes in such a way that overlap and scale changes bring the desired objects forward. In other words, the predominance of of our minds' edge-reading can override factors of temperature in paint.Stevehttps://www.blogger.com/profile/09596875722436085739noreply@blogger.comtag:blogger.com,1999:blog-2999230124118604245.post-56423137439027827242011-04-05T10:56:26.447-04:002011-04-05T10:56:26.447-04:00Hawk, I think you're right--it will also work ...Hawk, I think you're right--it will also work for a dark piece of paper or any flat shape, but color perception is especially coarse it works especially well with this trick.<br /><br />Dalibor, good question, and I've been wondering that, too. The first thing I thought of was the graphic device of putting a light colored line next to a black line, as David Lance Goines does on his posters: http://www.tbfa.com/ebay/goines/cp_red.html<br /><br />But I'm not sure how to apply it to traditional painting. Should we be aware that edges are more important than middles? What happens if you neutralize the center of a bright colored form? I'm not sure what to take from this either, but it's cool to know how our eyes work.James Gurneyhttps://www.blogger.com/profile/01870848001990898499noreply@blogger.comtag:blogger.com,1999:blog-2999230124118604245.post-5686560172155258442011-04-05T10:46:36.894-04:002011-04-05T10:46:36.894-04:00Hi James,

What is your take on that? Do you ever get to apply any such specifics to your painting. Thanks so much for posting such informative posts, your blog is a painting encyclopedia :)dddhttps://www.blogger.com/profile/04941060263659588619noreply@blogger.comtag:blogger.com,1999:blog-2999230124118604245.post-45785475123472366682011-04-05T10:43:41.429-04:002011-04-05T10:43:41.429-04:00Is that not the something as when you hold your ha...Is that not the something as when you hold your hand/arm 8 inchs to a foot from your face. When you do that it seems like you can see right through it but you still see the edges of your hand.
