در این فیلم، نگاهی خواهیم دیددر رمپ طیف،
که این مرد اینجاست این در پایین پنل رنگ قرار دارد.
و آنچه شما اجازه می دهید انجام دهید
به سرعت رنگ را برداشته است.
بنابراین، به عنوان مثال، اگر شما می خواهید یک سایه آبی،
شما فقط می توانید مکان نما خود را پایین بیاورید
به Ramp Spectrum
و سپس روی سایه ای از آبی کلیک کنید، مثل این است.
و این فقط پیش می رود و این ارزش ها را بلند می کند
و پس از آن شما می توانید هر گونه تغییر را ایجاد کنید
که دوست داری حالا شما نمی توانید انتخاب کنید
وقتی که رمپ این کوچک است.
و بنابراین اگر فکر می کنید خیلی از آن استفاده می کنید،
شما ممکن است بخواهید روی پایین بکشید
از پنل رنگ به طوری که
به منظور افزایش اندازه این رمپ.
و به این ترتیب، به عنوان کلیک و کشیدن در داخل رمپ،
شما خواهید دید تغییرات بسیار دقیق
در مورد من، مقادیر رنگ و اشباع.
در حال حاضر، توجه داشته باشید اگر مکان نما خود را بر روی این منطقه قرار دهید،
آن را می خواند HSB طیف،
00:00:51 assuming that you're seeing the HSB sliders.
00:00:53 If you click on the fly-out menu icon
00:00:55 and switch to RGB,
00:00:57 you're not gonna see any difference whatsoever
00:00:59 in the colors,
00:01:00 but when you hover your cursor
00:01:01 you'll see the Tool Tip RGB Spectrum.
00:01:04 And so if you wanna switch to the CMYK Spectrum
00:01:06 just go ahead and choose CMYK instead.
00:01:09 At which point you will see a big difference,
00:01:11 because the CMYK spectrum
00:01:13 is so much more muted.
00:01:15 Now, the thing is, if you wanted to map out
00:01:17 all of the colors that are available to you
00:01:20 here inside Illustrator,
00:01:21 then you would have to create
00:01:22 some kind of 3D map.
00:01:25 Because consider, for example,
00:01:27 if we're working with HSB,
00:01:28 I can go ahead and show all the colors around a wheel,
00:01:31 and just to jog your memory,
00:01:33 I'm going to go ahead and switch back
00:01:35 to artboard 2 inside of this document right here.
00:01:38 So we can show all the colors
00:01:39 wrapping around the circle,
00:01:41 and we can show the reduced saturation values
00:01:43 toward the center.
00:01:44 But if I wanted to show the different
00:01:46 brightness variations,
00:01:48 then I would have to turn this circle
00:01:49 essentially into a cylinder,
00:01:51 where black was at the bottom
00:01:53 and white was at the top.
00:01:55 And so when we're looking at this
00:01:56 2D representation right here,
00:01:58 there's just no way that Illustrator
00:02:00 can show us all the colors.
00:02:02 So here's what it does.
00:02:03 Regardless of whether you're looking at
00:02:05 the RGB, the HSB or CMYK spectrum,
00:02:09 you're seeing the hue values mapped horizontally
00:02:12 across this ramp,
00:02:14 starting with red over here on the left
00:02:16 and then we have orange, yellow, green,
00:02:18 cyan, blue, and so on.
00:02:21 Meanwhile, at the bottom of the spectrum,
00:02:23 the saturation value is 100%,
00:02:25 and the brightness value is zero.
00:02:27 Then we go up to the middle of the chart,
00:02:30 at which point the saturation is still 100%,
00:02:33 and now the brightness value has risen to 100% as well.
00:02:36 So in other words, the colors are remaining
00:02:38 highly saturated down here at the bottom of the chart,
00:02:41 but they're becoming increasingly brighter
00:02:43 toward the middle.
00:02:45 Then, once we cross the middle,
00:02:46 the brightness stays 100% all the way to the top
00:02:50 and the saturation value eventually
00:02:51 drops down to 0%.
00:02:53 So let's say we want to lift a shade of brown.
00:02:56 I would go ahead and click down here
00:02:58 in the dark oranges.
00:02:59 So orange and brown share a common hue value.
00:03:02 And so notice, if I click down here at this location,
00:03:05 and you can click and hold
00:03:07 in order to see the values update on the fly,
00:03:09 I just wanna make sure you're aware of that.
00:03:11 But at some point I'm going to reach
00:03:13 a hue value of 30°, let's say.
00:03:15 The saturation value will be 100%,
00:03:18 and the brightness value
00:03:19 I could get it if I tried hard enough
00:03:21 to come in at around 50%.
00:03:23 But let's say I don't want a highly-saturated brown.
00:03:25 Instead, I wanna reduce that saturation value
00:03:29 in order to achieve more of a kind of muddy brown.
00:03:32 This color right here
00:03:33 that has a reduced saturation value
00:03:35 and a reduced brightness value
00:03:37 is not found anywhere inside of this spectrum.
00:03:41 And so what's missing are all the colors
00:03:44 that have both saturation and brightness values
00:03:47 of 90% or less,
00:03:49 which accounts for theoretically 98%
00:03:52 of the colors you can define in Illustrator.
00:03:56 So, for example, let's say we want a pastel blue.
00:03:58 Well, if I click up here in this bright area,
00:04:01 you can see that the saturation value has
00:04:03 dropped down a little bit,
00:04:04 but the brightness value is 100%
00:04:06 and it's gonna remain 100%
00:04:08 as soon as we cross that threshold right there,
00:04:10 it's gonna remain at 100% all the way up
00:04:13 as you're seeing right there.
00:04:15 So if I want a shade of blue
00:04:16 that's a little bit dark
00:04:18 and it's a little bit desaturated as well,
00:04:21 then I'm going to have to adjust those values manually
00:04:25 using the saturation and brightness slider bars.
00:04:28 So in other words, this Spectrum Ramp
00:04:30 is a really great way to lift a base color,
00:04:33 but I don't want you to think that you're gonna have access
00:04:35 to every color you can create inside Illustrator
00:04:37 because, in fact, what we see here
00:04:39 are only about 2% of the colors.
00:04:41 If you want to get to the other 98%,
00:04:44 then you're gonna have to
00:04:45 manually modify the slider bars
00:04:47 whether you're working with the HSB,
00:04:48 RGB, or CMYK color model.
00:04:52 And those are both the strengths
00:04:53 and the weaknesses of the Spectrum Ramp
00:04:56 located here at the bottom of the Color Panel.
