Need Random Unusual Color/Gradients Combinations on Image

Hi,

I have FF5 and love it. I am looking for a filter that randomizes the color pallet or scheme on the image so would get many variations of color combinations. If a gradient component is included so much the better.

FF already has a random button and they were thoughtful enough to include a previous bottom! So the random function in not a concern here. I do abstracts mostly so would like to see unusual color combinations.

The saturation is controlled by the Gradient Saturation switch. If it is off, the output image uses the saturation from the original image. If checked, the output image uses the saturation from the gradient. Color Change.ffxml

Thanks for the super fast response.
I tried to find out how to install the
Color Change.ffxml but had no luck finding
out how. Please help.

Hi Rick,

I click on Color Change.ffxml and it open up the text in Google Chrome.

I have Windows 10 64 bit
I use File Explorer which was Windows Explorer
I have chrome and Internet explorer
Filter Forge 5 and FF Librarian 5.

In File Associations ffxml was and is set to Filter forge.

Searched in my FF5 and with the Librarian for Color Change.ffxml but had no luck finding it.

Really want to check out your Color Change.ffxml so lease advise.

Rick,

It was Google Chrome that created the problem.
Worked great with Internet Explorer.

Thanks for all the help.

I will now check out Color Change.ffxml and let
you know how it work out.

Hi Rick,

Apparently my message was lost in the bit world. I will attempt to re-write here.

I have huge image file and so for me time is a factor. Your Color Change Filter works very fast as it turns out. When I un-lock Color Smooth that is when it shows down. However when I lock Color Smooth your filter continued to be slow.

Now that Your Color Change Filter work so fast I am getting some interesting color combinations. I am sure there is more to this filter so I need to play around with it a bit more.

Thanks again.

However, many images do not need it, so you can set this to 0 (or a low value 5 or under), which as you have noticed is much faster. I have a couple of filters that I have written that do false coloring, maybe you can try them out: Channelizer Picasso Redux Over the next few days I will look at Color Change and think about more ideas on color manipulation. Have fun!

I have used both the Channelizer and Picasso Redux. Thanks for these usable filters.

I did better with not using the Color Smoother but will try low settings. Love how fast the color variations render in FF. Looking forward to any new color manipulation features.

Here is an update to Color Change. I've changed the Gradient Saturation checkbox to a Grey to Color slider which gives you more control over the grey areas. Here's an example.

Rick,

Thanks.

Color Change 2.ffxml is excellent. The gray is helpful.
Also I am learning how to use FF and this filter and this has been helpful.
The time factor was not all that bad. I go thru many
attempts in FF by the random button than to fine tune.

Looking forward t trying the Color Change 3.ffxml
But will be later tonight or tomorrow.

I am a bit confused on how to work the colors.
Is there an order to the colors? What is best to
be locked?

BTW initially I liked the Color Change 2.ffxml
and ignored the Color Change.ffxml but I
accidentally opened it and really alos like it.

Rick,

They do say be careful what you wish for. Now I am making TOO many variations on the color.
Good that you can’t put the Genie back in the bottle!

Thanks for the color advice. I am getting better at using this filter.

Is there a correlation of the color from the original image to the color Color Change filter

Is the Gradient Offset best on Color Change 1? On CC 3 I cannot get washed out or very light colors.

Is it possible to add metallic or chrome effects? A color to 3D effect?

Is there any way to get a gradient effect like from a light yellow to a deep yellow? Perhaps a gradient from one color to another? This will perhaps involve contiguous color range organization?

Another thing that I love is displacement effects perhaps to displace by color range?

Thanks for all the help.

Is it possible to add metallic or chrome effects? A color to 3D effect?

Yes. Instead of cluttering up the filter with more controls, try using the Surface Texture Engine. You can get metallic looks and 3D like effects. It is done with the lighting model in FF. I'll show you a couple of examples using the previous example. This one uses the default preset.

The light yellow to deep yellow is more difficult given how CC works. The filter takes the Brightness from the original image, so light to dark is not possible with the current method. I'll think about this long term. I think I've got you going now... I've got some other experiments going on in Chaos Fields.

Here is an attempt at a better explanation of how the colors are mapped. The original image uses these hue values: on the left, Red is value 0, on the right of this graphic is magenta turning to red, value 1. This is the classic spectrum (continued below):

In CC3 set the colors all to nearly white but the image was still bright color.
I Set the Gray To Color like you said and still full bright colors.

I then set one one color to bright red and red did not appear on the image.
I then set 2 colors to bright red and got a mostly blue image.

the bottom 5 settings: 2 32 30 3 10

Here we go again... I've changed CC as follows:
The Grey to Color control is now changed to GreyToColorToFade. The old method of coloring works by setting the control to 21. Color is 11. Grey is 1. You can fade between them. Setting Color Mix to 10 and GreyToColorToFade to 21 is your best bet for recreating CC1.

Color Change 4.ffxml

Why unfortunate?

I see. Yes, I understand what you mean.
Many times I'm busy all day and I start working on some filter when it is 1:30 am or 2:00. Ha! Ha! I remember that one time someone commented on a filter I made "Very nice, but why did you make it so dark?". Well, because I made it in the middle of the night, with all lights off, so.... it looked bright that time.

I have just found this and think is useful and interesting

Thanks very much Rachel for all the filters you have done
