I am finding the manual a bit hard to follow on the colour transform effect.
It says “suppose you want your character to hold her breath and her face to go from pink to blue”, which is pretty much exactly what I want to do; however, I don’t understand how you actually change the colour from pink to blue. I don’t understand the difference between the black “keyframe” squares in the brown colour transform bar, and the white “keyframe” squares.
My character’s face is white. I want it to gradually turn red - then, when he
gets his breath back, for it to gradually go back to white. I have added the transform element, attached the face element, and set the black keyframes, but this is where I get lost. What should I be sliding? the bars in the additive or multiplicative fields? And which ones to which values? Am I meant to know the numerical values of different colours in advance, and type those values in? When I adjust red, for example, the black outline of the face also turns reddish, which I don’t want.
Any help would be appreciated.
Thanks very much.
You seem to understand the process. The big difference between the Additive and multiplicative colors is the way that colors are created is not the same (it is just 2 different way to calculated the color, you should just go for one or the other).
As for the coloring of the line, the color transform automatically applies itself to the whole drawing, if you don’t want the color to be on the line you would need to isolate the lines on another element that is not affected by the color transform.
Okay, thanks for the explanation.
May I ask two questions?
1) What the difference is between the black and white keyframe squares?
Also, it refers to numerical values, which to me seems a bit abstract. I’m the sort of person who needs words like “purple”, “Pink”, etc., or pics to show what colours I’m changing or approaching. So:
2) Hypothetically speaking, if your character’s face is painted white in frame 30, and the colour transform bar starts there and extends to frame 50, how would you (either using the additive or multiplicative function) make his face gradually turn beet red (by frame 40), then gradually turn white again by frame 50? In other words, which sliders would you need to move to which values?
About the black and white keyframe I am not quite sure I understand what you are referring to. Where exactly do you see those different color pixel.
As for making the element go red or pink, if you start with a White color you will actually need to remove saturation of color rather then move the red cursor (a white color is composed of the maximum value of red, blue and green). Therefore you would need to go to that in between keyframe and bring the cursor of the green and blue value toward the left side of the properties window. This should give you a pink. The way to manipulate the Color Transform effect is more of a visual approach rather then something linked to the numerical values.
Thanks. I played around with it a bit more after my last post and figured it out. The problem I was having was that I had already changed the colour of the face element for the concerned frames from white to pink with the paint tool. I was sliding the bars back and forth, but the pink wasn’t really changing colour; just the black outline. When I repainted to white and tried again, I had no problem. I found that sliding the green bar backwards achieved the desired effect.
It’s not really important now I guess, but the manual (after describing how you can change a character’s face from pink to blue when she holds her breath) refers to “white blocks” as keyframes, and indeed, in the graphic underneath, the keyframes appear white. On the previous page of the same manual (version 4.0), and in my updated version of Toon Boom (4.5), the keyframes are described as and appear black respectively. I was just curious as to why they are suddenly referred to and shown as “white” on the next page of the manual.
Thanks for the quick help as always,
I think the screenshot you see in the manual is made of a selection of keyframe. When you select keyframe they usually contrast themselves to white, to reproduce that in version 4.5 you would need to start doing the selection outside of the color transform element and select the Color Transform keyframes. The screenshot has been made in a previous version of the software so the image itself may vary a little.
In any case glad you managed to make your effect work.
Does the colour transform effect only work if the original colour is white? It seems to work if I start with an area that is painted white, but if I use another paint colour, the sliders don’t seem to do anything.
Right now I have some puffs of smoke that are filled with a light, semi-transparent grey (opacity of 50). I attach them to the colour transform, add my keyframes and try shifting the sliders back and forth, but their colour doesn’t change at all.
Basically, I would like to have the puffs of smoke slowly drift off screen, and as they do so, slowy disappear. In other words, have the grey’s opacity slowly move from 50 to 0. Is this possible? Or do I need to recolour them all white to start?
Color Transform is an element associated with a drawing. It would be included within the the color transform element (parent-child). The keyframes are always black and are at the beginning and end of the end zone that appears by default, and can be modified in length like a peg. Any intermediate keyframe is added with + or - at the bottom of the window properties and its position is fixed, you can only add or remove a keyframe position. In Color Transform properties, sliders are in additive and multiplicative mode. You can use it as you like (optional). Always place the timeline red cursor on the keyframe to change color and transparency values. If the picture is painted in solid gray color, (like smoke) you can change it to another color in the next keyframe or make it transparent with the slider alpha and combined effects.
I hope that is helpful. Yoryo.
