Faces question
« on: October 18, 2015, 09:15:51 AM »
I have a face I created that is showing up purple instead of red. I am using .png for my format. Suggestions on changing this? Should I be using .jpg instead? Shows red in my xlights model but purple on the pixel tree.

Just had something similar for my Halloween faces...

I had to go to Paint and set up the RGB settings for the colours I wanted by the custom colour requester.

Then when saved as a png gave me the right output..

That worked for me too.
Thanks. I remember sequencing "War Eagle" and never could get the right color orange I wanted. Finally had to go into dmx settings on LOR S3 for the right color. Interesting that the model showed red and the actual output was purple.

Cool.
Glad i could help (for a change!??)

I originally used the orange on the paint tool bar, but it ended up an almost wishy washy yellow!
Then using custom colour settings got exactly the orange I wanted on the pixels..

What I hate is that I will be moving my "matrix" (copied after Sean) to my yard this week. Then I will have to sequence, run out into the yard to look at it, then go make my changes. Before, I just sequence and look up at the ceiling for real world stuff ;-)

I still can't figure out what you guys are saying is wrong.  I can tell you my colors on my matrix look pretty close to what I see in the sequencer.

Except for orange, i agree Gil, colors within the preview reflect actual lights. I've not gotten orange to look orange, it's always a yellow.

Gil

It is just getting the 'right' shade of colour in the PNG file so that Xlights displays the actual colour you want..
Some of it may be to do with gamma correction on particular monitors, but my matrix didn't produce anything remotely like I was expecting until I used the actual colour code I wanted through the custom colour requester in paint.

It's not a bug in the program, but in my case was an orange that wasn't actually technically an orange!!!!
More like a pumpkin that was a lemon.....

Now setting a custom colour in paint of red=255, and green=55 gives a nice orange on my matrix thru Xlights.

Yeah I know we don't really account for the actual colors you will see on an RGB string like LOR might be doing.  I know my SuperStar sequences used like 70% blue if you specified white.  But Red should never come out Purple.  None of the primary colors should ever be wrong on their own unless there is a node order or channel assignment issue.

I was more curious about whether the PNG that wasn't coming out right was created from xLights or another program.  I know PNG files can contain embedded color profiles which might be affecting things.

Gil,
Load that file I first put in.
Now load this file. I changed it in the RGB.

If you open your first in paint, sample the colour with the pipette then go to edit colours you see that your initial "red" was in fact:-
Red = 237
Green = 28
Blue = 36

as per attached screen shot.
The blue content is probably what made it turn purple??


Sample the second and you can see there is only the red component at 255
