Kisi bhi image ko dekho jaise protanopia, deuteranopia, tritanopia ya achromatopsia wale log dekhte hain — original ke saath, adjustable severity ke saath.
Color Blindness Simulator
Kisi bhi image ko dekho jaise protanopia, deuteranopia, tritanopia ya achromatopsia wale log dekhte hain — original ke saath, adjustable severity ke saath.
Color Blindness Simulator canvas use karke poori tarah aapke browser mein chalta hai. Aapki images device par process hoti hain aur kabhi upload nahin hotin.
Color Blindness Simulator aapka chart, interface ya photo un lagbhag 8% men aur 0.5% women ki nazron se dikhata hai jinhe color-vision deficiency hoti hai. Ek image drop karein, vision type chunein — common red-green forms deuteranopia aur protanopia; rare blue-yellow tritanopia; ya bilkul bina color wala achromatopsia — aur result ko original ke saath side by side compare karein. Simulation physiologically-based Machado transformation matrices use karta hai, jo linear light mein correct gamma handling ke saath apply hote hain. Severity slider un partial deficiencies ko cover karta hai jo kaafi zyada common hain. Agar aapke error aur success states sirf red versus green se alag hain, toh yahan ke tees second aapko exactly dikha denge ki ek color-blind user kya nahin dekh sakta.
Linear light mein apply physiologically-based simulation matrices
Mild anomaly se complete dichromacy tak severity slider
Original aur simulated view side by side
Har vision type ki prevalence noted
Reviews ke liye simulated image download karein
Color Blindness Simulator kaise use karein
Screenshot, chart ya design drop karein
Simulate karne wala vision type chunein
Partial deficiencies ke liye severity adjust karein
Panels compare karein aur zarurat par result download karein
Example
Input
Dashboard with red error and green success badges
Output
Under deuteranopia both badges render as the same murky ochre
Classic red-green failure — sahi aankhon se dekhe bina invisible.
Common errors aur troubleshooting
Simulated image lagbhag unchanged lagti hai. — Blues, yellows aur neutrals se dominated images red-green deficiencies mein achhe se survive karti hain — ye ek pass hai, khaabi nahin. Un screens ko test karein jo meaning ke liye red-green par depend karti hain.
Achromatopsia mein sab grey ho jaata hai — kya ye zyada extreme nahin? — Complete achromatopsia genuinely har hue hata deta hai, aur ye extremely rare bhi hai. Ise ultimate contrast check ki tarah use karein: jo grayscale mein survive karta hai, wo har jagah survive karta hai.
Results doosre simulator se thoda alag hain. — Kuch tools gamma correction ke bina matrices apply karte hain. Ye pehle linearise karta hai — published research method; differences zyada tar dark regions mein dikhte hain.
Aksar pooche jaane wale sawaal
Color blindness ke types ka matlab kya hai?
Protanopia mein red cones missing hote hain, deuteranopia mein green — dono red aur green ko ek jaisa bana dete hain aur har ek lagbhag 1% men ko affect karta hai, milder anomalous forms kaafi zyada common hain. Tritanopia blue-yellow ko affect karta hai aur rare hai; achromatopsia color bilkul hata deta hai.
Color blindness kitni common hai?
Lagbhag 8% men aur 0.5% women ko koi na koi red-green deficiency hoti hai — matlab jo bhi aap banate hain uske har baarah men users mein se ek.
Ye simulation kitni accurate hai?
Ye vision research ke Machado, Oliveira aur Fernandes matrices use karta hai, jo correct gamma conversion ke saath linear RGB mein apply hote hain — dichromacy preview ka standard approach.
Apna design color-blind users ke liye kaise banaayein?
Color kabhi akela signal na ho: icon, label ya pattern saath rakhein. Text contrast 4.5:1 ya usse zyada rakhein aur charts mein red-green ki jagah blue-orange palettes prefer karein.
