For fun bright spring shades, look tot he Shop MAC collection! The new collection includes five kissable lipcolour shades and I have swatches of three of them. MAC Kissable Lipcolour is a high pigment tube stain/color that wears pretty well. However it is admittedly a bit thicker than what I tend to prefer. I often go for more sheer shades. If you like the thick long wear types of tube color though, these are more likely to be up your alley.
Below are Scan-delicious, So Vain, and Enchantee.
And here are Shop MAC Kissable Lipcolour swatches of the three shades
As you can see they do have nice pigment to them.
