need help with this color

pat72

Hi everyone, i’m very new at painting. 

I’m trying to mix a sky color using only the primary colors: tita white, crimson red, ultra marine blue, cadmium yellow  (also have burn umber).
My goal is to use only these colors as I’m trying to follow the method from drawmixpaint and the color wheel. I must have watched the youtube video “how to match any color with oil paint” more times than I can count but no luck getting anywhere close to this blue. What am I doing wrong? I go through all my questions one by one (does it need more blue, yellow, red etc).
Any color I get is either to greyish or goes towards yellow. Even when adding very small amount before mixing. Spent a good 4 hours on this and starting to doubt myself. Maybe painting isn’t for everyone after all...

It's a dull green blue. I would have thought you could get that with the DMP colours. Mix Ultra marine blue and white until you get the value right, then some yellow and blue until you get the hue, then dull with brown and red.

Thanks for the tips. I did previously mix utra marine blue + white to get the value then I either added yellow, yellow-green or burnt umber/white but no good result. I’ll try again.

It's already on your palette. A mid value blue green. Maybe a little on the blueish? Cobalt?

not sure I understand. You see the light blue color of the sky in the picture I posted on my palette?
(maybe I need to get my eyes checked) 🤣

Kingston is right. In the photo you posted it's more of a mid-grey than a light blue. You should be able to match it from what I can see.

you find that the sky in this picture is a mid-grey?

I said more of a mid-gray

     I guess mid-gray it is (I thought mid-gray was more like the dab of paint I put on the picture). I guess my brain will have to be trained to look at colors more accurately.

Try cerulean blue with titanium white. Progressively add in specs of alizarin crimson until you achieve the grey level you seek.

1. Pure grey.
2. Your colour from the eyedropper tool
3. Same hue and value but maximum chroma at that value.
