In my later years, I'm starting to see that although I had previously loathed pink inks, there are some that are quite nice. Caran d'Ache's Sunset is at the top of that list for me. There is nothing I don't love about this ink. It's well behaved on Rhodia and CF paper, and has amazing shading. Overall, I can't say enough good about this ink. The main downsides are that it is fairly expensive (usually about $21 USD + s/h for 30mL) and that it is discontinued (though it seems to be an unpopular colour of this brand, so there's lots left still online). Several more up close shots of the yummy shading in my blog post here.
