Have been doing some grinding of chalk find on walks and tried pounding into old fabric (so old it breaks withing seconds of pounding). Tried a pale yellow and a reddish stone, then the leftover dried California Fushia flowers had from day before. Today , also used a few red rose petals, B vitamin tab, forget the purple (will go out and stare at it to see if recall) maybe it was a pink Oxalis?.
Have noticed, some f the stones will draw a diff color then they appear.

Had read on https://sunsikell.wordpress.com/ blog, who makes paints/inks, that a blue from algae, so read a little and wondered if the freezing mentioned in 1 study might work for me.
Had read on tartan authority about cress dying blue, but didnt get it - greenish on wool
While researching how that might have been done found info on a perennial sweet pea that think have in yard (no sweet smelling flowers though are dark pink). Also a "weed" that is Knapweed, went for a walk an found some. brought back a small stem (was only 1" or less tall, just spread out a foot. polygonum aviculre .
It was listed as a blue dye, so had to try it. Well after doing a flower pounding technique with it, leaves and stem were green ( nice ), Then noticed spots of maybe blue, dark, in the axils (?). Maybe is flower bud or flower? Went back yesterday and that side of road had been weed wacked.
If go to market today, may look for it on way to bus stop, also found Myrtle so am trying berries (leaves smell good). Do recall seeing Horned Goat weed this year, wonder if it does colors, would be nice to rid as punctures bike tires.
Sidetracked again as looking up what Mayan blue and Egyptian blue are made of .
Let me know what colors you get with natural materials. Will try painting/drawing next with the chalks.
