    Been TMU’d for colour blindness today at my medical (passed everything else). I couldn’t seen any of the Ishihara plates except the first 2 which were blatant to any one. I now have to go and take the trade test with the wires next week. Been trying to look at some posts about this test on the forums but most of them are quite old. I only struggle with red and browns in day to day life (snooker is an issue sometimes-banghead-).
    Anybody know if the colours are only primary colours and are they quite dark or bright? If they’re bright I’ll have no issues as I’ll just match them against each other.
    Cheers

    As a side note, I passed the same RM medical 18 months ago after failing the ishihara test but the doctor said ‘you don’t need to see colour for the Marines’ and passed me. Was this just laziness on his behalf?

    My son also failed the ishihara test at the medical and had to do the wire test. He struggles with green/red/brown. He passed the wire test a couple of weeks ago. He says they were distinctive colours.
    Do the ones you are certain about first then you'll eliminate some of the possibilities. Good luck

    They went through a phase of grading CP4 or better using the Ishihara plates but have now reverted to the wire trade test, leaving the Ishihara test for CP2.

    The colour expanse test (correctly identifying Red, Yellow, Blue & Green stationery tabs) is no longer used. The lantern test is used for grading CP1 & CP3.

    The wires include primary colours, orange, purple, black, white, grey & primary stripes.

    The tip is to make sure you take the test in good light - direct daylight is probably easiest. I have difficulty identifying light greens & blues, but passed the wire trade test OK.

    That said, as a mechanic they said I couldn't be an electrical engineer...until several years later they cross-trained us. After a few expensive bangs & flashes, here and there, it was decided that perhaps it was better employing me in a mechanical role.

    I digress, good luck.

    I couldn't get past the first 2 or 3 of the book, but I found the trade wire test was very easy.

    I'm not sure if it restricts certain specialisations, if anyone knows?

    Yep, Aircrew & LC. Aircrew need to be CP1, LC CP2.

    For those wondering, this is what a wire trade test looks like:

    It looks very intimidating to those of us with cp4 but if anyone is due to take one then my advice would be take your time, do the obvious ones like the black ones and the striped ones first, then go from back to front with those remaining.

    Thanks for this, I did wonder what it looked like!


    This is exactly the advice I told my son. Thankfully he passed

    Got my Trade Wire Test today. It's good seeing that picture of what to expect. Cheers.

    Are those the only two that colour blindness bars you from going into?
