Colour blindness - any ideas how to cope in the field?

Hi - I've started taking a mate out bunnying who has done a lot of target work but nothing in the field. I know he can shoot well but was puzzled by his poor success rate even with sitting ducks. Over a pint it turns out that he's red/green colour blind. So a brown bunny against a green background seems to have him stumped! Does anyone have any tips to help him discern rabbit over rabbit food? The only thing I can think of is to go at night and use the eyeshine.

 

Coloured filters .........use a digitscope by day (B&W contrast)....?????!!!!! Put out feed soaked with sunny delight so they go orange......????

 

He's a good mate and could do with some cheering up and loves his shooting so any help or ideas gratefully received!

Thanks for that - a sanity check that a B&W image might do the trick. Any cheaper ideas.....he's not got the dosh and my digiscope is sat on something else.

I wondered about 'spotting' for him with a laser level!!

Wow, never given this a thought! A guy who taught me joinery was released from the RAF Electricians during the second world war because he was colour blind, he was great with electrics mind;-) goes to show how we take sight for granted.

I know...when he told me in the pub that night it was a real clanger. My dad was a tankie and RG colourblind...guess all the Soviets had to do was paint their T-55's like giant bunnies and they'd have been well in! Then of course my -now-82- year old dad still drives like he's in something armoured!

OMG! Just something we take for granted, average sight. Let us know how you get on, I'm afraid I can't offer any help but if you get sorted let us know on here then we can all pass it on in the future. Have you tried all the top search engines on the internet? they do come up with good ideas at times.

As a fellow colour blindness sufferer (do I qualify for a blue badge?) I can say that I don't have any problem spotting bunnies as they are usually identified by shape or movement and not tone or colour. Incidently, wouldn't a black and white screen be a bit pointless if it us the colour and not tonal range that is the problem?

 

Do you 'normals' ever identify a rabbit by its colour? Seems a bit odd to me as rabbits come in all shades of brown, grey, black and white and so does a lot of cover.

 

Tell him to get a grip and stop making excuses, if he can see a rabbit enough to pull the trigger then missing has nothing to do with colour blindness.

No it converts from polychromatic (many colours) to monochromatic (single colour - that being black). By stripping out the reds and greens and leaving a pure monochrome image he will be able to distinguish the rabbits as the camera has done all the work!

Well not really, 'colour blind' is a misnomer, it is better descibed as colour deficiency where you see the colours but not quite as clearly or as accurately as others. Taking away the colour will reduce your ability to distingush between colours but leave only the tonal range whereas leaving the colours will not only leave the tonal range but leave the (albeit diminished) colour range too - if anything a high saturation screen would be better, but still a waste of time. I am red-green colour blind and also a photographer and ex professional colour printer btw.

That is my lads main problem area, and when he went through PILOT selection it unfortunately resulted in a medical failure!

Same, sort of, when I was in the air training corps I wanted to be a pilot, when I found out I couldn't because of colour blindness I was a bit peed off.

I have an HND in Printing Management, which included a hell of an amount on the physics of colour, both primary (RGB) and secondary (CYM).

 

Swapping from Poly to Mono will enable the eye to resolve the tonal range much better without the confusing of similar areas because of reflection of light wavelengths that the particular eye cannot differentiate between! As the eye in question has a difficulty in distinguishing between red and green, the camera will do this and display what is different colours as a different percentage of black on the screen, thereby enabling the eye to differentiate between grass and rabbit.

We'll have to agree to disagree on this one! In the field, and from experience, 2 colour deficient eyes are better that one black and white one.

 

I still think it's just a convenient excuse for missing really....

Look at the snooker balls on a snooker table! The red and brown are both easily differentiated from the green table on a black and white tv!

Well, as I said we'll have to agree to disagree.

 

The second image has had all saturation removed so the tonal range is unchanged. Good job rabbits aren't yellow....

i have been colour blind all my life, green/brown blue/purple and a few others all look the same. when at home i ask my other half and kids what colour things am and they still take the **** out of me. i work by shades now not what colour they are lol. i still wire up 3 phase motors at work and i even wired the factory up and installed the fuse boards when we moved to a new place. just guess it works for me lol

I have been colour blind all my life , failed the colour blind test in the army but got 100% with the GPO colour blind test, the army did the card test with loads of spots and you had to say the number, GPO done the test with different pieces of wire with multi colours which was easy for me as I do see shades better than most, I was a paint sprayer for 25 years contracting all over Europe, painting everything from the queens plane to Aston martins and Richard Branson's trains, done a lot of new cars that were damaged before they were sold and I could never work in a spray booth doing the blowins on panels as I could see the difference in shades, colour, call it what you like, it looked like black and white to me.

On a snooker table I can tell you all the colours and I get caught out on red and brown depending on the shades on the balls as each set of balls are different.

I can see rabbits ok but must say my shooting mate can see them much quicker than me.

I have asked about my colour blindness and was told and do agree that I remember the shades and colours, it might sound weird but I no grass is green and the sky is blue and stuff like that as this is what I've had to do all my life

Well fellas I started this thread to try to help a mate out not have a pop at his competancy. Perhaps my post misled with the 'sitting duck's bit but the truth remains that he says he is struggling to see rabbits in the field.

 

We've done loads of range stuff together on my land and he can shoot well. He had lots of CF experience until he lost is FAC for medical reasons. He's hard enough on himself without someone sniping that he's a **** shot. This forum is here to share experience and help one another but so often it becomes the domain of less than helpful remarks. Falcon I understand you might be OK and that's a perfectly valid point but please don't chuck the unhelpful stuff in.

Thanks for your efforts - my sight is pretty good so I have no concept really of what colourblinedss is like. Maybe he is making excuses. Perhaps the move from target to claret is all a bit too raw and he's not happy and not taking the shots but I have to take what he says at face value.
