Applying custom colors to guides in "Guides manager"

[Bad_Wolf]

Hi,

It should be a nice feature if we can apply custom colors to different page guides.

For example, page guides who mark the location of a text frame color blue;
page guides who mark the location of images color red.

It should be a very usefull feature if we can choose our own custom colors for individual guides in the guides manager. RagTime has this and it makes layouts much clearer when used correctly.
