View Full Version : Chase RGB Colors Horizontally Having Weird Effect

A group of cells 1 high by 11 wide. All single cell effects. All at 100% intensity. Right-Click Change RGB Colors Horizontally and selected Red (#FF0000) for start and "Dark Red" (#800000) for the end. Instead of getting a graduated ramp down from 100% Red to 50% Red, what I got was 100% red in the first cell, and then what appears to be black ramping up to 50% red at the far right.

Was getting something similar when doing the same thing but choosing 100% red for start and black for end, but it was 100% in the first cell and then ramping up from black to 90% red on the far right.

BTW, the same thing happens when using the horizontal chase from the HLS Tool Bar.

Did you rebuild the preview after changing before playing?

Why are you doing a Color Chase --- You are asking for an Intensity Ramp.

Use Ramp UP or Down ---- Select 100 for your RED and 50 for your Dark RED.

Mainly because I don't wavy to do the math to figure out the graduated values for the intermediate cells. I know I don't have to do it for the ramp, but I want to copy specific cells to other channels, say the third

(Not fond of tapa talk...)

Anyway, say i want to copy just the seventh cell in an eleven cell ramp to another channel and not have to calculate that it's at 37%. That's why the chase as opposed to the ramp. If chase wasn't designed for this type of abuse, fine. I can do the math. Just looking for a quicker way.

When you ask for a Color Chase --- you get one of two ways.

#1 --- around the color wheel --- so your RED to Dark RED would go through a lot of different colors depending on what direction around the wheel you went.

#2 -- The way you chose is to fade from one color into the other --- through BLACK --- which is mostly what you have with a 50% RED for Dark RED.

Doing the math is easy ---

Convert from HEX to decimal --- so your FF is 255 and your 80 is 128

Now its a ratio

255/100 = 128/X

Rearrange X = (128 * 100) / 255

X = 50

Yes it is pretty trivial, but I also haven't done a very good job of making myself understood.

I was going to describe a much more complicated scenario where I was doing something similar over a larger range, but as I was typing it, I realized I was to focused on intricacies asked that yes, I can live with ramps even though they might not line up perfectly.

This is NOT a hobby for some with OCD. But it does teach one patience. ;)

Thanks again for everything, Joe.
