SPLIT GEL | Specifications | Instructions | Applications | Color Theory | Help

Everybody knows how to use gel. You select the color to enhance the mood you want to convey, slide it into a gel frame and place it in the gel frame holder in the front of your instrument. But sometimes you find you need a subtle mix of colors to achieve the look you want, such as a sunset, water or a stained-glass window effect. Sometimes you feel the need to add extra excitement to a pattern.

These effects are easily attained through the use of split gels- various pieces of gel taped together. The light from an instrument will blend the colors a little bit, but you'll still get enough separation of color to achieve some interesting and unique looks. There are endless ways that colors can be used together to achieve a myriad of looks. It is important to note that a split gel will look entirely different depending on which way it is inserted in the instrument, which instrument and beam spread is being used, even which pattern you are using with the split gel. A stained-glass window split will have three different appearances when used with three different window patterns.

That said, let's look at the various ways a split gel can be arranged.


1. Standard Split Gel.

Using G810 Moon Blue and G320 Peach, tape together straight down the centerline. This is a widely used style of split gel, and works well for sunsets, or just about any other two-color effect.

2. Sandwich Style Split Gel.

G730 Azure Blue paired in a "sandwich" with G1516 .6 ND provide an interesting stormy look. As with the standard split above, any two-color effect can be achieved this way.

3. Quartered Split.

This split can be achieved by either quartering sandwich style, as shown, or standard style. Dividing up the colors in this way makes the color separation and blending more dynamic. This works well for moving effects. G850 Blue (Primary) and G250 Medium Red XT, shown here, can be seen in action in the Recipe Book Video entitled "Sunburst".

4. Multiple Split Gel (Fire).

This split gel uses a variety of reds oranges and yellows to give fire it's multi-dimensional hue. Any variation on these colors and any taping technique can give added realism to your fire effect. Some good fire colors to try include G280 Fire Red, G290 Fire Orange, G355 Amber Flame, and G450 Saffron. Remember- go easy on the yellows. A little goes a VERY long way.

5. Multiple Split Gel (Gas Fire).

Using the same technique of mixing fire colored gels, add a small amount of blue-green such as G710 Blue Green to give the appearance of a gas jet creating a flame.

6. Multiple Split Gel (Water).

Water looks best using both lighter blues and cyans. You can also mix in a few no color spots to add the appearance of reflection. This one was created by using a hole punch to randomly remove bits of color from two gels- G710 Blue Green and G780 Shark Blue, and then taping the two colors directly over each other. A bit of colorless light escapes the gel at various points. This is good for providing a surface water effect.

7. Split Gel (Water Variation).

A small circle of G760 Aqua Blue is applied to a hole cut in the center of G725 Princess Blue. As the beam of the fixture spreads out, the two colors mix together to suggest deeper water.

8. Multiple Split Gel (Autumn Leaves).

Using G315 Autumn Glory, G390 Walnut, G410 Yellow Gold and G570 Light Green Yellow, arrange and tape to suit your personal aesthetic. Overlapping colors slightly in this case works for you, facilitating the blending of various hues to give your fall colors effect depth and realism. You can create a spring branches effect by taping a variety of greens together using the same technique.

9. Multiple Split Gel (Stained Glass Window).

Using heavily saturated, almost primary colors, and again your own design preferences, (these colors are G650 Grass Green, G915 Twilight, and G140 Dark Magenta) Tape together to create a stained glass window effect. Keep your color pieces chunky and don't overlap too heavily, or your colors will blend too much to look effective. Use more pastel tones to create a spring flowers or butterfly wings gel, but remember to use colors that are distinctly different from each other to avoid them all bleeding together to create one muddy color.

10. Center Pool Split Gel.

This variation on a two color split (G342 Cantaloupe and G140 Dark Magenta) helps to supply shading and visual interest to just about any pattern. Try it with an amorphous breakup, or even with a pattern such as 329 Atom. Using a split color with one of GAM's moving effect units, such as the TwinSpin II, will make the colors appear to blend into and away from each other. Letting colors overlap slightly will increase this effect.

11. No Color Split.

Leaving gaps of no color in your split gel can either lend highlights or help to define and separate colors. You can remove a section of gel directly from the center, like this one (G235 Pink Red and G815 Moody Blue), or you can try removing various bits from several points in you split gel.

12. The Artistic Split.

This "designer" split gel is really only for show. You won't actually see in the light the patterns you create with the gel. In terms of function, color placement is more important than overall gel appearance. This one uses G140 Dark Magenta, G420 Medium Amber and G780 Shark Blue. Use your imagination to create fanciful patterns for split gels that may be in audience view, or that you feel just need a little artistic vision.
