  3. When someone is color blind it doesn’t mean that they see no colors. It’s not like they see everything in shades of gray except in very rare instances. Being color blind means that you have trouble seeing red, green, yellow, blue or some combination of these

  6. I only made out 12 and 3. A pity I work with colors on very expensive machines. It is my well kept secret. I got some other advantages in life though. I just have to explore them now.

  13. Thanks for the test, it's very helpful to have multiple color plates to test from. If anyone is having trouble with their color vision, and are looking for treatment for colorblindness, I recommend trying the ColorCorrection System, which has a 100% success rate at passing the Ishihara Color Plate Test....

  15. In some of these, I can see both answers superimposed, and I'm confident that I'm not color-blind (since I use broad and fine color distinctions extensively in my work). But I can imagine scoring low by picking the wrong one during an examination, or by refusing to pick just one owing to both options being equally strong to me. What do examiners do in cases like that?

    1. Just a tad random there.
      I think these tests are a little over-difficult. Sitting in front of a tv doesn't help the situation, and with everyone watching tv or on their mobile contraptions I fear we'll all become partially color blind.

  22. I think that these tests should be used on an individual basis. I have been an offset press operator for over 32 years. I can see color density's that very by 1 or 2 points by eye on a multitude of colors but cannot answer all of these tests correctly.

  23. Good luck to all of those of you who failed the test. I feel for you, even though I'm not color blind myself.

  61. कलर ब्लाइंड’ ( colour blind ) की बीमारी से छुटकारा
    मेरा नाम एम बहादुर है अपनी नौकरी के लिए आर्मी (एन.डी.ए.) में गया था। जहाँ मैं शारीरिक परीक्षण में तो पास हो गया। परन्तु मेडिकल परीक्षण में मुझे कलर विजन में गड़बड़ी (सी.पी.टी) होने के कारण निकाल दिया गया। इसके बाद मैंने अपनी आँख का इलाज कराने के लिए उज्जैन के आई सर्जन डॉ. जैन को दिखाया। जहाँ पर मुझे डॉक्टर जी ने यह कह दिया कि इस रोग का दुनियाँ में कोई इलाज नहीं है। जिससे मुझे व मेरे परिजनों को बहुत निराशा हुई। और मैं निराश रहने लगा। मेरा आत्मबल लगभग खत्म हो गया। मेरी हँसी गायब हो गयी। क्योंकि मुझे फौज में जाने का बचपन से मन था। कुछ समय बाद मुझे लॉ मिलिट्री अकॉदमी के संचालक श्री अरूण जी ने ब्रेन ट्रेनर प्रो एन एल श्रमण मेमोरी गुरू आप्फ़ इन्डिया , के बारे में बताया जिनके यहाँ से कई छात्रों ने इस बीमारी से छुटकारा पाया है। इसके बाद में मैंने अपना इलाज श्रमन जी के यहा मात्र 1 दिन करवाया और बाद में घर मे अभ्यास किया जिसके बाद डाक्टर को दोबारा दिखवाने पर उन्होंने कलर ब्लाइण्ड का रोग ठीक बताया। इसके बाद मेरा आर्मी हॉस्पिटल दिल्ली में दोबारा परीक्षण होने पर मुझे आर्मी के लिए फिट कर दिया गया। और कलर विजन भी सामान्य बताया गया। मैं इस सबके लिये प्रो श्रमन का सदैव ऋणी रहूँगा। मुझे यहाँ ब्रेन मैपिन्ग सिस्टेम से पढाया गया । अधिक जानकारी इस वेबसाईट से की जा सकती है www.colourblind.in व www.ishihara38.com
