Interesting, that test case has not been changed in years... maybe a difference in the last few digits is dependent on the architecture of the machine you run it on, or the node/V8 version? 🤔

[0, 0.1, 0.2, 0.5, 0.8, 1].forEach(t0 => {
		t.deepEqual(
			interpolate(['red', 0.5, 'green'])(t0),
			interpolate(['red', 'green'])(t0)
		);
	});

Is this the only test that fails?

Its the only test that fails.
I'm on node v16.9.1 / osx 11.6

It this ends up being the issue you could add: { "engines" : { "node" : ">=whaterver" } } to the package json

I've tried running the tests in GitHub Actions, and they pass even with Node 16.9.1, and I can't reproduce the issue locally on macOS 11.6 (M1 processor) with that Node version installed...

It's also bizarre in that interpolate(['red', 'green'])(t0) does not produce that color value for t0 in [0, 0.1, 0.2, 0.5, 0.8, 1], which seems to be the value of interpolate(['red', 0.2, 'green'])(0.5).

@danburzo I've done some testing :D
So.

node v9.4.0 => npm run test => pass
node v10.19.0 => npm run test => pass
node v11.0.0 => npm run test => pass
node v12.0.0 => npm run test => color interpolation hints fails
node v13.0.0 => npm run test => color interpolation hints fails 
node v14.5.0 => npm run test => color interpolation hints fails 

I did not continue at this point but I am currently on v16.10.0. I am using n as a node version manager. But I have an Intel Mac.

[meodai]

I am infinitely sorry for having wasted your time: this is the version I was actually testing: https://github.com/meodai/culori :( The updated version/tests pass just fine :(

Please let me know where to send beers / coffees

Ooh 😅 no worries, glad it's sorted out!
