Blending
Ah, the age old subject of \"perfect\" blending! I can help you here....
The way to blend is to \"feather\" the line between the paints so that there is no sharp contrast between colors - done correctly, you can even blend black into white!
The main problems are two-fold: Firstly, acrylic paints dry too quickly and second, it is very difficult to describe in words! The best way is to see someone else do it, and then copy them!
In order to blend correctly you need to use the correct type of paint. Personally, I NEVER use Games Workshop paints because they dry FAR too fast - colors like white can go \"crumble dry\" before you even get the brush on to the figure you are painting! At the minute the best acrylic paints are Vallejo Acrylics. They are made with no alcohol in the medium and do not dry as quickly. Enamels are also quite fast drying, I prefer acrylics for the base coat. Oil paints are ESSENTIAL if you want to get a completely smooth finish!!!!
The best way to blend is to decide on the overall color - then pick a slightly lighter color and apply the base coat. For the next part you will need a bottle of \"flow enhancer\" - this is a specialist art product that can be mixed with acrylic paints and makes them stay \"workable\" for about 12-15 minutes. \"Flow enhancer\" is not expensive, I get mine from a local art supply store - a 75ml jar will cost you a whopping $5.00 or so, easy enough to get hold of! Most \"big\" paint companies make it, Daler-Rowney, Windsor and Newton, Cryla, etc. (I have used all 3 mentioned above, they are the same). It is best not to rely too heavily on water as it only dilutes the overall color and doesn\'t really extend the drying/blending time. (Be sure you buy the correct flow enhancer though - there are acrylic flow enhancers, enamel flow enhancers, etc.)
After the base color is applied, leave it for a couple of hours to harden. Then decide on a darker version of your base color - whether you simply use a darker shade or mix your own is up to you. Once you are satisfied with the dark shade, mix in some flow enhancer. Personally, I use about 1.5 parts flow enhancer to 1 part paint (you will just have to use trial and error to determine how much you want to use - different paints have different pigmentations). Then \"wash\" the figure and let the dark color get into all the recesses etc. (you know the rest). Now get a cotton bud or simply tissue paper and CAREFULLY lift off some of the \"wash\" from the upper surfaces ONLY. This will allow some of the base color to show through on the raised areas. If you accidentally lift some out of the recesses simply put some more back in! Be aware though, you only have about 12 minutes maximum before the paint/flow enhancer mixture starts to harden, so for large or complex figures, paint one area at a time. The end result will be a figure that is overall darker than the base coat, with the recesses darkest of all.
After the wash is COMPLETELY dry (leave it overnight - flow enhancer takes 12 hours or so to harden) you will see that the raised areas are darker than the original base coat, and the recesses will be very pronounced. Now it is time to highlight!
Take some of the base color and start to apply it to the raised surfaces ONLY. As the paint drys very quickly, you will need to work FAST and do one section at a time (e.g., start with one lower leg front, then do the lower leg back or sides, then move to the next area). In order to blend you have to feather the line between the colors. That is, put your highlight color on one small area, then use a clean damp brush to soften the line between the two colors. Some people use two brushes for this, I have been doing it for so long I prefer to use just one brush. I quickly give the brush I am using a swirl in a pot of clean water and dab off the excess water on a bunch of wadded tissue. The end result is that my brush is damp and contains a small trace of the highlight color, which I feel helps with the blend. If you do it quickly enough (i.e., BEFORE the paint starts to harden!) then you will see the sharp line between the two colors dissappear! If you find that the paints are drying too quickly, add a LITTLE flow enhancer, not too much or you will end up with a wash again!
It goes without saying that the closer the two colors are in the first place the easier it is to blend. For example, dark red with medium red highlights is far easier than blending green into yellow!
At first you may not notice much of a difference, especially if your highlight is very subtle (e.g., dark and medium red are very similar). When the highlight is COMPLETELY dry, feel free to add a lighter layer if you wish, and so on until you end up with the desired effect. I cannot tell you how far to go, you will have to decide for yourselves. I try to use between 4 and 7 shades in total, I know some people who say they use over 130 shades! I do not believe them however, because you have to remember that each layer adds to the amount you are covering the figure with - after 130 shades (even if they are all washes!) I don\'t think there would be very much detail left....
If you want it to look expert you will have to spend time and patience on this - it can take anywhere from a couple of minutes to a couple of hours for EACH shade, depending on the size of the figure, the level of detail you are going for and your own ability! I mentioned oil paints earlier - oils are far easier to use because their drying time is a couple of days, not a couple of seconds!! They are fully workable for around 2-3 hours so there should be no problem blending, even for the least experienced or slowest painter! Fast drying oils take about 3 days to dry, medium oils take about 8 days and slow drying oils take 11+ days to dry completely, unfortunately each shade can be different, so read the label! On the bad side, oils are VERY expensive! I live in England and a small tube costs about £5.50 (about $10.00) and can go up to £45.00 (approx. $90.00) for 1 tube!!! When I say a \"small\" tube, the smallest oil tubes my local art store sells are about 4x bigger than an enamel or acrylic \"tub\" and the paint itself is about 100x more concentrated, so it will last you for about 6+ years, even if you paint all the time (like me)! To thin oils you need a bottle of linseed oil, about the same price as flow enhancer mentioned earlier. You can get linseed oil quite cheaply from a grocery store, but it is not \"pure\". It is best to pay the extra and get refined linseed oil from an art store. You will also need a new set of brushes - keep the ones you use for oils and acrylics well apart! Acrylics can be cleaned in water, oils need to be cleaned in turpentine substitute. (It is best to wash the brushes with warm soapy water afterwards to get the turps off! This makes them last a lot longer and keep their points!)
Although oils are expensive, you do not need every color - in fact I have only 24 oils compared with over 300 acrylics! Oils are extremely easy to blend, and every oil shade will blend with every other!
Needless to say, blending with oils is stupidly easy and it also produces the best results, but remember you will need to wait for two weeks for the paint to dry before each successive layer so it is not for the impatient! (Also watch those fingerprints!!!)
Well, I hope this is of use, if you need any more clarification just give me a shout!
