Features & Capabilities

Chromatic Vision Simulator is a color vision simulation tool that reproduces how people with common color vision deficiencies see the world. Developed by Kazunori Asada (Ph.D. in medical science and Ph.D. in media design) and grounded in color science, it models cone-cell mechanisms to predict color perception and can generate simulated images of protan, deuteran, and tritan vision types from your camera or photos in real time.

This educational tool supports real-time viewing, helping students, designers, and educators understand perceptual differences and create more accessible visuals by testing color choices across inputs.

User Reviews

Chromatic Vision Simulator is widely praised for real-time, camera-based colorblind simulations and a simple, no-frills interface. Reviewers value its educational use for explaining colorblindness and its usefulness for design, UX, and signage testing. Recurring concerns include realism not always matching actual color perception, and privacy/permission issues around camera and photos, with occasional crashes and save problems. Calls for clearer explanations of color-blind types and better ongoing maintenance. Overall, a powerful but imperfect tool.

Pros

Real-time colorblind simulation via camera, allowing users to see what colorblind individuals perceive.
Simple, no-frills UI with multiple colorblind type options and support for both camera and photo library input.
Strong educational/communication value for explaining colorblindness to others and aiding family or colleagues.
Valuable for design, UX, branding, and signage testing to improve accessibility.
Ability to compare multiple colorblind types/settings in a single view for demonstrations.

Cons

Realism of the simulations isn’t always perfect and may not fully match actual color perception.
Privacy/permissions issues around camera and photos, including reluctance or failure to grant access and related bugs.
Saving/export limitations and bugs (difficulty saving snapshots; no easy video export; occasional save issues).
Stability/maintenance concerns (perceived lack of updates and occasional crashes).
Usability gaps such as unclear in-app explanations of color-blind types and terminology.

Recent reviews

If you know a bit about color blindness. You know it’s some cones of color perception overlap. But I feel like the app just assumes the entire wavelength the cones pick up overlap based on which colorblind type you pick. So my mom just assumes all reds I see are brown but I’ve never mixed up a red and brown in my life. It’s good for picking up girls tho

as someone who’s colorblind, i get the question “what color is this? what do you see?” a lot. Whenever this question gets brought up i just show them this app and let them look around. The reactions are always fun and it’s always interesting to hear what they have to say. It’s really helpful understanding what i’m missing out as well. The reactions from other people tells me that i see the world in very dull colors.
