2d:null 2e:["$","title",null,{"children":"Color vision deficiency simulation | Dan Burzo | Observable"}] 33:T4b9,md`[\`culori@0.11.0\`](https://evercoder.github.io/culori/) comes with functions for simulating color vision deficiencies: * culori.**deficiencyProt**(_severity_) simulates protanomaly (for \`severity ∈ (0, 1)\`) and protanopia (\`severity = 1\`); * culori.**deficiencyDeuter**(_severity_) simulates deuteranomaly (for \`severity ∈ (0, 1)\`) and deuteranopia (\`severity = 1\`); * culori.**deficiencyTrit**(_severity_) simulates tritanomaly (for \`severity ∈ (0, 1)\`) and tritanopia (\`severity = 1\`); Based on the work of Machado, Oliveira and Fernandes (2009), using precomputed matrices provided by the authors.
