Logwood Persian Berries Eco Dye Pots

Sometmes natural dyes can prove to be very difficult to photograph.  Once or twice I have run into real problems getting the colour of the dye into the camera.  A Logwood dark blue will never come out the colour I see it as.  Today I have dyed some wonderful lime greens  and purples with Logwood and Persian berries but no matter how I photograph it it comes out grey with flashes of purple..  Oddly enough the Persian berries greens look grey in artifical light too  See for yourself-and you will have to take my word for it that this  does not do justice to the colours at all what  you see as grey on the screen is  a lovely green.
