here are the two colour charts I have made up for promarkers/flexmarkers.
The first one is for the standard promarker colours and the second one is for all the current standard promarkers and flexmarkers together
All you need to do is click on the pics above to take you to the download site. You then download the chart(s) for free.
I recommend that you print the chart(s) onto the same cardstock that you use normally with promarkers/flexmarkers - then you can colour in your chart(s)
By using the same cardstock that you normally use for colouring, you ensure that you have a true representation of what each colour will look like. (You'd be surprised how different each colour can look on different types of cardstock)
You can also print the chart(s) onto copy paper to keep in your purse/handbag as a handy reminder of the colours you still need to collect.
