I have no idea why the Tetenal chems haven't been mentioned yet, so let me be the one who does. As far as color is concerned, they make C41, E6 and RA4 chemistry kits which are sold in central Europe. In Vienna, Austria there are two brick and mortar stores which have C41 and E6 in stock and if they are out of RA4 they will order it (especially Blende7). Numerous online shops also carry these kits.

As far as Ilfochrome is concerned, I found a retailer in Graz which will order the Ilfochrome chemistry plus the paper upon request. While their webpage states they will not ship any orders, they will ship even internationally if you contact them beforehand (according to a phone conversation I just had with them).
