Body
the issue is that you want something like a distance on a 3 dimensionnal world, but that rgb representation is not intuitive at all : 'near' colors can be much different that 'far' color. Take for instance two shades of grey c1 : (120,120,120) and c2 : (150,150,150) and a now take c3 : (160,140,140) it is closer to c2 than c1, yet it is purple, and for the eye the darker grey is much closer to grey than a purple. I would suggest you to use hsv : a color is defined by a 'base' color (hue), the saturation, and the intensity. colors having close hue are indeed very close. colors having very different hue do not relate one to another (expl : yellow and green ) but might seem closer with a (very) low saturation and (very) low intensity. ( At night all colors are alike. ) Since the hue is divided into 6 blocks, cyl = Math.floor( hue / 6 ) gives you the first step of your similarity evalution : if same part of the cylinder -> quite close. If they don't belong to same cylinder, they might still be (quite) close if (h2-h1) is small, compare it to (1/6). If (h2-h1) > 1/6 this might just be too different colors. Then you can be more precise with the (s,v). Colors they are nearer if both low/very low saturation and/or low intensity. Play around with a color picker supporting both rgb and hsv until you know what you would like to have as a difference value. But be aware that you cannot have a 'true' similarity measure. you have a rgb --> hsv javascript convertor here : <a href="http://axonflux.com/handy-rgb-to-hsl-and-rgb-to-hsv-color-model-c" rel="noreferrer">http://axonflux.com/handy-rgb-to-hsl-and-rgb-to-hsv-color-model-c</a>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
