Never Stick Your Elbow In Cadmium Yellow!
First, even though it's your elbow, you'd be surprised how many places on your body it can actually reach!
Second, because although it is one of the most luscious yellows available in oils (my opinion, but a common one, if just for it's superb clarity and high tinting strength in mixing), it is TOXIC. Which is why one should always wear an over shirt or at least a painter's apron. You really don't want the cadmiums on your bare skin.
Third, it is a Grizzly bear to get out of fabric precisely because of it's tinting power and intensity.
I wasn't even using it very much at present in the portrait I'm working on, except for making small touches of various complementary and reflected greens, but it's very expensive to my budget, so I don't toss even a dab if it's still workable, I just move it to the new palette. It takes a long time to dry, so will often be viable when other colors left out longer than intended between painting sessions are dry all the way though.
Don't ask me how I got my elbow in the very small pile of yellow that was waaaay up in the upper right corner of my palette. I dragged the shirt sleeve through it at some point, then leaned my elbow on my thigh. By the time I noticed it on my jeans, I thought "Oh crap, where's the rest of it?!" All over my favorite painting shirt, which is over sized on me so a bit more prone to this type of studio accident, but I posted my love of this shirt at length in a previous post, so I won't go there.
I took it off, my jeans too, and used my brush cleaning solvent to remove as much as possible, then soaked it in Chlorox 2 and left it for overnight (I'll let you know if it works). That's the one advantage to having a studio space in a laundry room. That may also be part of the problem: my work space is so tight and small that there is not enough room to really manage a larger canvas, and this is not even big, only about 16" x 24". I used to favor 3 by 4 FEET. Those days are over, at least for the time being. As difficult as it is, as much as I was spoiled by "real" studio space over about 35 years, I bless my small area and I am glad to have it. As I downsize all the stuff and bother of my life in a quest for greater simplicity, less overall expense and more peace, thus ending up with less and less material "stuff", I find it's so much easier to be thankful for the smallest of things, which makes the bigger stuff truly awesome!
I went online tonight needing bigger brushes for this particular work, picked out about $80. worth, left it to go paint some more, spot happened, came back up to rework the order, then checked my credit card balance, and decided I couldn't afford it. BUT, I am really grateful I have a computer to go online with to even browse!
So, all two of you reading this, take a moment to count all of your blessings! :~D
