We recently discovered this great online color palette tool that had all of us in design giddy about it. You can create all kinds of palettes for online use, from mono to complementary and beyond. The contrast and saturation levels can be adjusted and previews are available to show you your palette on light and dark page templates. The tool also features an export function which allows you to export your palette to photoshop, HTML/CSS or XML. Additionally, the “Vision Simulation” option lets you preview your palette through the eyes of people with color blindness and other vision impairments, a great feature for assessing accessibility concerns.
