Using too bright material colors in Ecotect is not possible?

[george_1985]

Hi,

I was trying to add the new material in Ecotect 2011 (in fact edit the old one, just changing it's color) by using this Ecotect Wiki tutorial:
http://wiki.naturalfrequency.com/wiki/Create_New_Materials

I wanted to apply the following color to my new material: Papyrus white (code name: RAL 9018 HEX: #D7D7D7). But then I got the:

WARNING: Value is unrealistically high.

By playing around with the "Surface reflectivity" slider I noticed that once it passes the value of 0.83 (or 0.84 something, I am not sure) a previous (WARNING: Value is unrealistically high) warning message appears.

This made me confused. Does this mean that too bright (in terms of color) material colors can not be used in Ecotect 2011?

Thank you for the help.
