That is: if you want to help me ...
I see number 5...
The person without color blindness sees the number 3, the person with color blindness deficiency sees a 5. If the deuteranomaly is total, the person will not see any number.
I get to the point, since I don't think you care (rightly) to know about me 
There are many, really many common, normal stamps ... that I can't identify correctly.
For my color blindness.
If I don't bore anyone, and especially if you let me, could I post my very simple stamps here?
Better still, I already post some catalog alternatives (especially Colnect) and tell me what my stamp is, so I can immediately associate it with the Colnect catalog number.
Can I do a single test?
In my opinion it is Mi: YU 1206
What do you tell me?
Thanks so much!!

Interesting example. If I understand the choices on Colnect I would not know the differences between orange and red orange. I am not color blind (I see the 3) but I was never good a shades especially when you add a not very scientific method of color naming in catalogs.

Thanks so much!! Looking at the two examples on Colnect, I would agree that this looks to me like Mi: YU 1206. I am also not color blind; I can see the "3". And yes, there is no problem with your using this thread to make posts asking for help with color identification.  |

Please do keep posting your items, some one will always reply,
Colour is a problem we all come up against. Experienced collectors agonise for years over colour and shade . Sometimes the difference is trivial, sometimes the catalogue values are substantially different, sometimes it is impossible as colours change with age, dirt, atmosphere, sunlight or simply due to the settings on a scanner or computer screen.
It is not easy to decide is a stamp red- brown or brownish -red, pale green or light green etc etc . So even with those of us with no colour differentiation issues you may get disagreement.
One eminent member of my philatelic Society was totally colour blind, and a red overprint on a green stamp or a black overprint looked the same to him. He gave up worrying about colour altogether and had fabulous postal history collections of all the tiniest local post offices , railway Mail, steamer and paquebot mail as well as extensive complete George Vi collections, where again his main interest was in the post marks .
So to answer your question , of course a colour blind person can collect stamps…….it just demands a different approach to collecting……don’t get hung up on colour or shade , there are other things in stamps to enjoy.
But post any questions you like. That’s what the forum is about.

I think even for a person,what is not colour-blind,it will be very difficult to decide by a scan, wether this is Michel no.1233 or 1207. The difference between carmine-brown and red-brown is not that significant. Would help a lot,if both stamps would be scanned side-by-side !

Sure. If I had all kinds of these stamps. If I had both types, obviously I would have posted both of it. It will certainly happen ... with some cedars of Lebanon that I have  Thanks so much! |

I see a 3, but I agree that color is one of the most difficult issues in cataloguing stamps. And who in their right mind used the word "lake" to describe a reddish color stamp? another one, how do you discern ultramarine from blue. It's things like this that really mess with your mind.  |

I have SG colour keys in front of me - Blue is blue with its different shades, Ultramarine is darker and can even be deep ultramarine !!!! |

Their are software programs out there that can show collectors different colours, like below.

I see that there are color differences in the four stamps. More than anything else shades. I see the differences in the rectangles below, but I am unable to associate the colors with those of the stamps.  |

He had to fill out a test, the result of which was that I am 60% color blind, if I remember correctly ...

I laugh at some of the colour varieties of stamps. Especially the DDR. What, pray tell is the difference between red-brown and brown-red? How can one tell, besides the ridiculous price of one over the other? I generally don't bother with shade varieties as many factors can alter them. They are, after all, very old in most cases!

Let me say one thing.. For those who believe they are NOT colour blind...Let me set this misconception straight
Everyone CAN be affected to colour blindness...Let me explain, i think i am not colour blind..BUT...As a employee of a major telephone company, i used to have to spend 20 to 30 hours repairing telephone cable which were colour co-ordinated...After hours of working on coloured telephone cable and not having rest/sleep, you do become colour blind...What i mean a repairman would have trouble with colours like RED/ORANGE colours...etc.
There was a study done in England that said you could look at a colour, have lunch and it affects the eyes as per seeing certain colours and the sunlight VS darkness affects colour interpretation.
That is why i am helping BNAPS with their new "Digital Philately" study group assisting them with software with reguards to stamping...The 3 colour number "3's" was done with one of my software....They are linux based [and free] and can be adapted to those of you who use Windows/Mac.
Enjoy Robert
Below are 3 examples of many that can help stamp collectors enjoy stamp collection....Just saying.

Quite simply, I am interested in trying to correctly identify (referring to the numbering of a catalog) a certain stamp. If I can, fine. If I can't, I won't make a tragedy of it. But I want to ... at least try ... |

I am red-green colorblind. My workaround is to ask my Wife what color she sees when I'm having a problem.

The Ishihara is a much bigger test than that one image, it's not very good for anything but a pre-test, and any color test taken on an uncalibrated computer screen is largely irrelevant. And to make it worse, no two people see colors exactly the same way anyhow - it is mathematically impossible. However, the digital age gives colorblind people workarounds. First, there's a thing out there called the Munsell test (100-Hue test) that will give you a much better idea of how colorblind you are, and in which direction (color perception is a bit more complicated than most people realize). Knowing that information has been immensely helpful in calibrating my monitor by allowing me to overweight and underweight the green and red appropriately - essentially, my monitor shows me stamp images color-corrected for my vision (yes, I'm "colorblind" too). I go to great lengths to color-manage my scanning and imaging processes, but using my own scans and computer I can now tell at a glance the difference between stamps that look completely identical to me under natural light. But tomiseksj 's workaround is definitely valid - women are 1/10th as likely as men to have noticeable color perception problems! |

Don't be too hard on yourself. When it comes to color identification, having perfect vision doesn't always make the grade either. Color differentiation in philately is arbitrary, difficult and subject to a myriad of factors that can alter the color of the original stamp making accurate color identification a minefield at times.

Quick answer: of course you can collect stamps, even if color blind.
It will make it a bit harder, esp when trying to identify shades.
Please feel free to post your pictures - you'll get fast replies.
Colors are hard on the computer/internet even if not color blind, so it may not be perfect! But my guess is that for 90-95% of your stamps, folks will be able to ID correctly & you'll be in good shape.
That last 5-10% - for all of us - is a challenge!!

Sorry - just realized I was replying to a post that was 6 months old! (Reading-blindness!!)
Colors are a definite pain...would be much easier if all the stamps were just black & white!!
