Watercolor Lemon Reference Image
Lemon Watercolor Pencil Drawing
I start off with an outline pencil drawing using a mechanical pencil. I prefer the mechanical pencils as you get a uniform line every time and it never needs sharpening. Also, if you carry it around in your bag, you don’t get graphite over everything which gets very annoying after a while.
The reference image has a grid on it and, if you’re not confident in your drawing please use the grid. I generally grid up the photos into quarters and size the reference to be approx 9″x12″ or 11″x14″. This makes it easier to grid up your paper without doing any convoluted math.
If this were an oil painting we could happily draw the grid on the canvas in the knowledge that the opaque paint would cover it up later. With watercolor we can’t do this as it’s a transparent medium. I find that even if the graphite lines are very very faint they still leave a faint mark when you erase them which we don’t want. To avoid this and still benefit from the grid I put a dot where the grid lines cross. This gives me a reference dot which is useful but doesn’t show up after we’ve put the paint on.
I have many more step-by-step tutorials and videos!
A lot of the basic skills in watercolor painting involve seeing and mixing colors of the right value. To help us with this I’ve adopted two tools used by many other people but in particular Paul Foxton (whose workshops and classes I highly recommend).
A Value Scale is An Invaluable Tool
A good accurate value scale is a great investment and they’re really quite cheap so there’s not much of an outlay. I recommend the Paul Centore value scale which has 20 steps and has highly accurate neutral grays.
A Color Isolator Helps us See Color And Value
The other thing is the rather grandly titled ‘color isolator’. This is just a piece of gray card or paper colored to a mid value with a half-inch square cut from the middle. When we place this over a reference image the gray gives us a buffer between the color we want to see and everything else around it. The mid-value gray also gives us a hint as to the value. If you download the image above you can print this on your own printer. At a pinch painting a piece of card with a value 5 gray and cutting a hole in it would also work well.
Using our color isolator and value scale we can work out two important colors and values: one for the part of the lemon in the light and one for the part of the lemon in the shadow.
Using the color isolator and the value scale together we can work out the two important values. In this case we have around an 8.5 value in the light and a value 6 in the shadow. These two values are enough to create a convincing lemon. The only other thing is the highlight which is so light we can leave white paper for.
The ChromaMagic Tool Can Tell You The Hue, Value, and Chroma
If you don’t have a printed reference the ChromaMagic tool can tell you the color of any region of your reference. Just download the reference photo and go to chromamagic.com and load it up using the button in the top right corner. Clicking on any region of the reference will display the exact color of that pixel. It uses the Munsell System to show the color which is extremely useful for us painters. The Munsell system separates each color into hue (red, orange, green etc), value (light and dark), and chroma (how gray the color is) which makes it more straightforward for us to mix the right colors.
Fabulous tool to find the color and value in *any* reference photo. Basic version is free to use.
Give it a try now! The best way to use it is to have a guess first before clicking on the reference. Your color perception skills can improve in an extremely short time by guessing first then using ChromaMagic to check your guess.
