Since the post I have googled some about daylight led:s temperature and it seems that the question does not end there.
Daylight color is actually a range of colors (you can see the colors when the water separates the colors of daylight and produce a rainbow). The colors of the fabric you see is actually the light from the bulb that gets reflected. So if you do not have a light with e.g. a lot of the blue range of colors you will have a hard time seeing differences in the blue fabric you are using.
So to see colors well I think it would be good to have a natural light led with good range of colors.

Now I just have to find a producer that makes a daylight bulb with b15d connection.
