Playing with bitmap fills and color
Hi there,
I know that there has been some insight about colors on bitmaps fill using the RGB matrix (great) sheet effect but I don't know if a procedure has been detailed.
Here is how I've done it on the map below.
On the leftmost map, I just have the map in the plain solid colors I wish.
The center map has the nice bitmap fills from the M. J. Roberts annual. However they are far from the target colors from the left map.
Now all you need to combine both is a picture editor that gives you RGB value and allows screen capture. I use Photofiltre, which is free...
1. Open the solid color map (left) and make a screen capture
2. Select the color and read the RGB values, in my case Red 182 Green 225 Blue 133 for the land color.
3. Do the same for the bitmap (center) map and chose a medium color tone. I got Red 199 Green 199 and Blue 137
4. In CC3, on the bitmap (center) map, apply the RGB matrix effect to the relevant sheet and type following numbers in the matrix :
0.910 - 0 - 0 - 0
0 - 1.131 - 0 - 0
0 - 0 - 0.971 - 0
You get the map on the right : same color as left, same texture as center !
What are those numbers ? They are the ratio of the target_color_value/bitmap_color_value, ie 182/199 = 0.910 for Red , 225/199 = 1.131 Green and 133/137 = 0.971 blue
This method will however only work on bitmaps where the colors are near, ie shades of a single hue. On more complex bitmaps, the results may not be satisfying...
The effect IS a matrix after all, and solving advanced math (or trials-errors) can probably yield fantastic alterations...

Note that I have two sheets for the sea, and both with the same fill style. The RGB matrix settings are quite different though...
The land sheet uses the \CC3\Bitmaps\Tiles\Overland\Annual Jonathan Roberts\Grassland.png fill style and the attached MyLand.txt RGB matrix setting (rename to MyLand.ColorMatrix, which the forum doesn't accept)
The shallow sea sheet uses the \CC3\Bitmaps\Tiles\Overland\Annual Jonathan Roberts\Sea_Light.png fill style and the attached MySee.txt setting
(Deep sea uses the same fill style with transarency and blur effects)
Forests sheet uses the \CC3\Bitmaps\Tiles\Overland\Annual Jonathan Roberts\Forest.png fill style and the attached MyForest.txt setting
Note that this last fill style is at 1:5 scale (ie the other are scaled with 500x500 and the forest fill style is scaled with 100x100, on fill style properties)
Thank you very much.
The mountains symbols (not a fill style) and fill styles are all included in the 2011 annual '(march issue):
