I'm trying to make assign colors to individual segmented lines using ROI Manager. Every time I make a selection and change the color in properties, the line reverts to its original color as soon as I click back on my image. How can I assign colors to individual lines and get them to stick? Thanks

I am working within Google Earth Engine and am trying to create a no-color/completely transparent color (no boarder and no fill). Below is a line of code where the first color should be the transparent "color". Basically I want my min value to not show up in the map at all.
Map.addLayer(image, {min: 0, max: 3, palette: [transparent, '#0571b0', '#FFDF00', '#ca0020']},'image');
I have tried creating a variable to set a color as completely transparent (change the opacity to 0), but the palette command cannot take variables. Only strings. I've also read SVG fill color transparency, but do not understand how to change the opacity of that specific color without creating a variable (which again, palette doesn't allow). Lastly, I tried adding 00 to the end of another color, but that did not work either.
Any suggestions?
Update:
I was never able to find a solution to this and ended up just going with a white back ground. It was purely for a nicer aesthetic look to allow a basemap to be seen. If I ever come across a solution, I'll be sure to post it.
I had the same question. I found the solution in the developer group.
See the answers: https://groups.google.com/g/google-earth-engine-developers/c/WcxtEIzudxw/m/GscOlsQhDgAJ
The Solution:
// create your previous mask
image = image.eq(1)
// mask and set the opacity
image = image.mask(image.mask().where(image.eq(0),0.0))
I have drawn route between two places with 3 waypoints, I need to set green colour from starting place to first way point, then blue colour from first way point to second way point, likewise I need to set different colours based on waypoint. Any help.? TIA!!

Is there anyway to remove the black border from a TColorbutton ? Delphi xe5, developing for iOSdelp
There are actually three black or gray borders.
First, add a custom stylebook to your app. The docwiki tells how to do this:
http://docwiki.embarcadero.com/RADStudio/XE5/en/Customizing_the_Design_of_a_FireMonkey_Application
Follow step #2 (Step 3 doesn't work for mobile applications.)
Open the style editor and locate ColorButtonStyle.
Expand the tree node and click on "background" in the structure.
In the object inspector locate Fill and expand that node.
Change the fill Kind to bkNone.
That removes the wide gray bordered, leaving two dark gray 1px borders.
Further down the list of properties just below Sides is Stroke.
Change it's Kind to bkNone. That removes the outer gray line.
Depending on your app you may need to also edit the color animations below the background rectangle. I did this by erasing (blanking out) the triggers since I was unable to delete the animations.
Next go the Fill component and set the stroke kind to bkNone. That removes the inner gray line.
You may also also want to set the Fill Margins to 0 so the color extends to the outside of the object. (i.e no padding now that the gray is not there.)

I have chart showing time data. I have two points back in time which I need to "mark" in the chart.
I currently indicate these two by plotlines, but would like to show bar, with let's say green and blue bars showing the timespans (for example -13days from now with blue and -90days -> -13days with red).
I would use plotBands, but I can't specify their height and do not want to have them all over the chart.
Is there some way? I saw something about translating pixels and drawing rectangle, but wasn't able to make it work. Also - I zoom a lot in this chart.
You can use Renderer and add custom shape. In other cases, please attach mockup of your goal.

I need to modify the focus-box's border color of TVirtualStringTree,
just like this pic:
You can't control the color of the dotted focus rectangle. That's determined automatically by inverting the color of whatever it's drawn on. The OS provides — and the tree control uses — an API for that. (You could edit the source code and replace calls to DrawFocusRect with your own function, if you want.)
If you're talking about the color of the whole node, then first check to make sure the toUseBlendedSelection paint option is set the way you want it. It defaults off, but since it makes the selection rectangle look cool when dragging a box around items, you might have turned it on without realizing what it does to ordinary selected nodes, too.
If that's not it, then adjust one of the values in the tree control's Colors property, probably either FocusedSelectionColor or UnfocusedSelectionColor. But please don't make such a change lightly; the user has chosen the selection color through the OS options, so you probably shouldn't change it. If you do use a different color, make sure the text is still readable against whatever new color you select.
You can set treeview's option toHideFocusRectangle to true and paint your focus rectangle by yourself in one of several paint events (basically it is enough to use OnBeforeCellPaint).
