Hi, All. This may well have been done a hundred times already but I thought I would post it anyway.

I've been having trouble getting my colored pencil sketches to have the same depth and realism as my graphite sketches. I finally decided a big part of the problem is that I am a poor judge of the value of a color. Graphite is easy, of course, because they very conveniently label them by value.

Anyway, I made a couple of value charts of the pencils I use most frequently. This is the best one, although it, too, is subjective. I might move a couple of colors up or down a notch, but it's close enough to help me. Maybe it will help someone else as well.

Cheers,

Herb

First the color scan (far from perfect):

Then the grayscale version:

Herb, This is well done and an excellent idea to put the chart in grayscale and have them side by side for comparison and guidance. I think it would be worth my time to do the same for my pencils.
Thank You for sharing this with us.:thumbsup:

This graphite grisaille guy who is using Coloursofts is very grateful!

Thanks you for time you put in on this, Herb. It's a great idea! Like Paula, I think I'll do this for my Prismas–and my FC Polys.

What a great idea doing a grey scale.
Thank you

I'm glad someone else will get some help from it. It took me a couple of tries, and it could use some refinement.

I found it easiest to first just make a chart of my colors and the graphite without trying to organize them. (If I could have organized them I wouldn't have needed the chart! :D ) I then scanned these and converted them to grayscale.

Here's the part my wife found a bit odd...

I then cut out all the colors (with their identifying numbers) as individual swatches. Then it was just a process of matching each value to the corresponding graphite swatch.

After I had them all layed out as best I could judge, I colored a complete chart on a new piece of paper, scanned it, and converted it to grayscale. Those are what I posted.

There can be a lot of variation depending on how hard you press, how many times you go over the area, your scanner, and so on. But, I think it gets one close enough for government work. :D

Cheers,

Herb
