    Why is there two Trans-Purple? #37 and #52; BL use the same but like you pointed out they don't allways have the right answear, but imo if they don't match it's worth looking into. If there is two different colours then one need to change name atleast slightly.

      I got Nathan to add the other one a while ago, you're the first person to notice. I'm getting colours sorted for RB2, and our existing trans-puple was the wrong RGB value, and looked terrible. It was also conflated with trans dark pink, and trans light purple, due to us using BL data in the past. It's being slowly fixed, and I'm going to add a forum post soon, begging for further information on some pre-2002 LEGO colours.<br>There are going to be cases where we will not match BL, and I don't care [as we can fix everything on export/import]. I'd rather we were accurate than in agreement.<br>The main accuracy issue is BL using far less colours than LEGO, and pre 2002 it's really really hard to find decent information that's trustworthy for colours. This will get better, I've just discovered I need a new colour [Medium Reddish Violet] that BL call Dark Pink, but isn't in any catalogue.

        Can't help you much with colours, almost all my LEGO is in one of the basic 7 colours. The only exception is some fabuland pieces and a few bricks i got recently. and many of my pieces hasn't aged so well when it comes to colour. but almost all colours has shifted tone over the years. Red changed quite alot when they switched from AC to ABS. Blue seem darker now then it was earlier, light grey has also become darker before they switched to light blueish grey.

        not sure how much the "ageing" of the brick is involved in the colour shift compare to original colour.

        I can tell you this much, the "frosty" molds that BL used for some trans-clear bricks, is just showing up regular mold changes over the year. and isn't actually worth their own parts. Unless your going to start splitting basic bricks molds alot.

          Agreed - we have to draw the line somewhere splitting parts into variations. I have combined some of the co-injected LURPs and BURPs into one, as they were never handed for example, the mould 'differences' at BL are simply due to piece position in the mould, not due to differences in the actual pieces.<br>For colours we will call red 'red' if LEGO called it Bright Red [#21] even if it has changed slightly over the years. Yellow used to look a lot more custardy too. Mould variants won't really be sorted til RB2 is up and almost fully fixed, I expect we will be removing some variants from inventories, but NOT from the catalogue as some people like a really accurate record of their parts.<br>Re: frosted interiors - I can't be sure this was ever deliberate, or just a side effect of a mould having a rougher internal finish.

            Yeah you will need a fourth option during builds if you want to include purists.

            Pure, exact, close,ignore.

            4085 is one part that people for some reason has been very picky with. if we would be as picky with all parts there would be alot of mold subtypes.

            "exact" needs a good guideline and so will mold splitting. RB need to draw a line and explain where it is so the community can contribute with somewhat same accuracy.
