This would create association between the color & the name, as opposed to the color and the bucket that the vertical line creates. Also take the feedback from Patrick very seriously. Color blind is far more common than consideration is usually given for.http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment27http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment27Tue, 19 Mar 2013 14:50:47 GMTI have to say as a red/green and blue/green color blind person, these abstractions are not useful to me.http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment26http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment26Mon, 18 Mar 2013 20:52:51 GMTThomas, It isn't the number of entities in a collection that colors it. It is the total number of entities collections.http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment25http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment25Mon, 18 Mar 2013 16:33:12 GMTThere's only one User and one BlogConfig, why are those colored then?http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment24http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment24Mon, 18 Mar 2013 14:54:35 GMTAre these color blind safe colors?http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment23http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment23Sun, 17 Mar 2013 09:33:52 GMTAh, that makes much more sense now! Indeed, I was puzzled by rainbows on six different entities on the screenshothttp://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment22http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment22Sat, 16 Mar 2013 19:30:47 GMTMax, It seems that I didn't communicate something clearly. We start with simple colors. Then we move to composite colors (2). Then we move to 3 colors, and so on. The first few entity types are always going to be solid, then there are going to be entity types with 2 colors, etc. You only go to the crazy part if you have dozens or hundreds of entity types.http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment21http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment21Sat, 16 Mar 2013 18:15:57 GMTI guess it is one of those things. Don't knock it until you try it. Is this a 2.5 thing?http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment20http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment20Sat, 16 Mar 2013 13:05:32 GMTAyende, I'm not sure if that is the best way to distinguish multiple types. I'd prefer solid colours than rainbows. For example it is hard to distinguish Posts and Commenters. Once you look on it long enough, you get it, but that's not the point here. On the other hand, dark red and light red would be easy to tell apart.http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment19http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment19Sat, 16 Mar 2013 11:39:27 GMTSam, They don't _mean_ anything. This is just a UI hint to make it easier to tell which documents belong to what type.http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment18http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment18Sat, 16 Mar 2013 05:23:51 GMTKhalid, This isn't a joke. The psychedelic colors only kick in when you have _hundreds_ of entity types. At that point, you need some way to get things working. And while it is difficult for us to notice the differences in those mode, it turn out it is easy to tell them apart.http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment17http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment17Sat, 16 Mar 2013 05:23:05 GMTItay, Configurable is a source of trouble. It is "I don't know how to do that, let us let the user decide".

I guess thats the point Ayende is trying to make. When model reaches certain complexity, it should be divided to simpler separated and isolated models - Databases. (In terms of DDD, which RavenDB supports out of the box, bounded-contexts)http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment11http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment11Fri, 15 Mar 2013 18:57:55 GMTAbsolutely no idea what these colors mean.http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment10http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment10Fri, 15 Mar 2013 15:05:47 GMTha, so I'm not the only one who read this in the morning and went 'whaaaa?' http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment9http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment9Fri, 15 Mar 2013 14:32:24 GMTI have no idea what I'm looking at...http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment8http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment8Fri, 15 Mar 2013 14:16:14 GMT@jbland agreed, i don't know what's going on... cool looking though...?http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment7http://ayende.com/161250/ravendb-and-storing-large-number-of-entities-types-in-a-single-database#comment7Fri, 15 Mar 2013 13:20:53 GMTis the difference in the two images the number of color bands on each collection type?

I don't get it why psychedelic colors (although cool looking) would make the experience any better, I think it makes it a bit harder.
