At my stamp club this month one of the techniques was Emboss resist. We did the one in Pretty in Pink. I then found these 2 other cards I had made in Perfect Plum and also Lavender Lace. After embossing your images in white on whisper white card stock, you then sponge over the whole piece of card in your chosen colours. I prefer soft subtles for this technique but I am sure it would look ok in the darker colours.
