Cross stitch companies with coloured charts?

[SeaSunSand]

Asking on behalf of my nan. Shes 72 and loves cross stitching. Her eyesight isn't what it used to be and she finds it easier to follow a coloured chart. The only company she knows of is Joy Sunday and she's done most of them. What other companies use coloured charts?

All of mine are black and white. The only thing you could do is get the charting paper and do them for her in colour?

The alternative would be doing tapestry in half cross, with a preprinted coloured canvas, so Ehrman, The Historical sampler Company, Emily Peacock etc
