My go-to color links (general color theory stuff): - https://paletton.com/ palettes with color theory and can generate the entire scheme. - https://medialab.github.io/iwanthue/ I want hue, uses k-means to separate out colors, great for graphs and getting contrast on those. - Source: Hacker News / 5 months ago

Looks useful for gradients. Strange that nobody mentions Paletton. It's my go to tool when picking colors: https://paletton.com/ You start with the base, and then also get gradients to adjacent colors in the palette. Especially the triad and tetrad ones are useful. - Source: Hacker News / 5 months ago

In terms of coming up with a colour scheme I like paletton. Source: 12 months ago

Could use a pipeline to this one website that scans colors from images and states their name, could be a quick new command like a special screenshot that is sent and scanned then named. Or a phone camera color scanner? There are also other websitesthat could be useful.. Whatever it is, I bet it could work out. Source: about 1 year ago

At Scale we built a tool for model debugging in computer vision called Nucleus (scale.com/nucleus) designed exactly for this, which is free try out if you're curious to see where your model predictions are most at odds with your ground truth. Source: over 2 years ago

To address your point about gathering edge cases, which can also be defined as cases of low model fidelity for our use cases, there is active learning and tools such as Aquarium Learning and Scale Nucleus which make it easy to implement into workflows. Source: almost 3 years ago
