sadly I have to say: forget this chart. I remember the few colors I tried on saturday, and those didn't match to the old ones.
for example:
- baal red is a LOT lighter, than carroburg crimson. (altough here I felt, that the baal red should have this darker shade from the beginning)
- nuln oil is more like a mix of badab and devlan.
- mecrite red is darker and more brown than mephiston red (I also liked this change)
- ultramarines blue has a bit of purple in it, altdorf didn't have any. For me altdorf is more like magic-blue. (after seeing in the store(and the gw website too), that UMs are not painted with UMBlue paint anymore it doesn't really matter )
- Lyaden darksun is lighter and less orange than the averland sunset.
- iceblue - lothernblue is about right
- whites are well, whites, no problem here
the rest I don't remember.
also the chart itself is bad in this way: caliban-green equals both orkhide shade and DAGreen? well those 2 don't have the same shade.
The chart is more like: if you used color X you can use color Y instead (what not said is: but they won't have the same shade, so your army after this point will look different than with the paints before.)
