Usually when graphic designer want to check if his print is ok for colorblind people they just change it to grayscale. If there is enough contrast and the message is readable then it's (usually) ok for all kind of colorblindness.
I have a "colorblindess" in part of green spectrum. A very dark green is not seen by me as green. On screen it's Black(-ish) and ...
This is only a comment, but too long to be written as a comment.
The causes of color blindness vary. The color selective sensor cells in the eye have color filters which make them able to coarsely make difference between separate wavelengths. The wavelength ranges of the filters are wide and they overlap, but the processing in the brain makes possible to ...
Lasers tend to be inferior to inkjets for raw color reproduction, especially on the low end (i.e. less than $25K).
That's because inkjets can cleanly render a single dot, allowing them to use sophisticated dithering schemes that finely spread microscopic dots (in the 4 or more ink colors available) all over the area in question. Not are the individual dots ...
Few days back I was in similar situation. Here is what i found.
open the pdf file in illustrator. I am hoping the file you have is vector.
Select everything ( control + a or Cmd + a )
Go to Objects > Flatten transparency
Preset - High resolution, Raster /vector to vector ( refer the image
Voila! your rgb file is now CMYK
Ok, you have to understand that color as precieved does not have anything to do with wavelengths. Its true that different spectral spikes make different colors. But that does not mean all same looking colors have same spectral distributions, unlike what quick glance in physics let you believe.
Simply CMY colors are the very closely the same wavelengths as ...
I have seen this many times recently, where many so called "oh i can use Figma and Sketch" designers produce these random, meaningless logos in RGB or with fonts not outlined (which gives errors on opening), or both. Then they deliver this to the client in PNG.
Because, you know, everybody's hates Adobe and their monthly plans, but luckily we have Figma and ...
You need to explain to your client that all colors on screen (RGB) can not be reproduced on paper with ink (CMYK). One is a subtractive color model the other additive.
There's no "magic" or "trick" to make an RGB color which is outside the CMYK gamut reproduce as the same color with ink on paper.
The only options are to find an acceptable CMYK color, or ...
IF all the objects have the same Gradient applied to them..
Simply select all the objects and make any adjustments you wish in the Gradient Panel.
Common gradients can be changed in unison by merely selecting the objects.
Change the gradient as you want on one instance;
Open the Graphic Styles palette (Window > Graphic Styles or Shift+F5;
Drag your correctly gradiented object into the palette to create a new Graphic Style;
Select all other objects;
Click the Graphic Style in the palette.
For the future only: Drag an object to the Symbols panel. From there you can drag multiple instances of it to the artboard. Edit the original in the Symbols panel or one of the instances on the artboard. All instances will get the same edit including the gradient.
Since you are looking for a tool, I'd like to suggest GIMP because it's free, Open Source, and cross-platform. You could also do the same in Photoshop (but it's not free).
Create your artwork in GIMP (or Photshop) using as many layers as you want. I used the Pen tool to create nice smooth selections, and filled them with basic flat colours. Using a large ...
Yes, you certainly can!
It's called a vector mask, when you use a path as the mask.
Draw a vector path with the pen tool, and click Layer > Vector Mask > Current Path
If you already have a vector shape on its own layer, put the image on a layer above and Alt/Option+click between the two layers to clip the image to the shape below.
Yes, that's called a mask. You have a layer with the glitter image, another layer with the vector shape, and with these you can create a mask:
We have got two samples how the wanted colorfulness ranking method should work: Colorless BW photo should give a low number and a rainbow which has some colors which at least on a normal sRGB screen look quite bright and saturated should give a big number.
You have already got a hint to redirect your activity to a scientific website and to use CIELAB color ...
It is not possible to copyright a group of colors as far as I'm aware.
It's possible to trademark colors as part of "trade dress". However, trademarks are not the same as copyrights. And even if trademarked, you are free to use any color theme outside the industry which any trademark applies. So, unless you are building or advertising a subway/underground, ...
If you have a 'live' gradient applied to an object within Illustrator, you can generate a set of flat swatches by selecting the object and clicking the 'edit gradient' (in the gradients palette). Add some nodes to the gradient wherever you want a new colour. Then, go to your swatches palette and create a new colour group, using the 'from selected artwork' ...
I am not certain it's possible to directly glean the original color from a baked-in flat file.
But, I think you can make an educated guess...
Duplicate the layer and set the duplicate layer's blend mode to Multiply. Then zoom in and watch the pixels, duplicate the multiply layer repeatedly until you see a pixel (probably in the center of a stoke away from ...
If you know you want each item equidistant, you can use tabs.
Merely select the type and choose Window > Type > Tabs from the menu. And set tabs to all be the same distance. And, of course, have a tab in the text between each item.
This keeps all the type on a path on the same circle, making editing easier at times.
You can also use the Paragraph ...
Do Object > Transform > Rotate on the text on the path, rotate it 30 degrees, press "Copy" to make the first copy. Press Ctrl/Command+D to repeat until you have all the text.
Edit the text with the text tool.
I was looking for a similar tool and found this: http://vrl.cs.brown.edu/color
It automatically generates palettes up to 20 colors and has some settings to fine-tune the palette features like "Perceptual Distance" between the colors, which are very useful.
I know it does not handle 50+ colors but I can't find anything better: what I'm personally doing to ...
This may not be available for every type of brush, but try double-clicking that particular brush in the 'Brushes' panel and push the 'Paint Opacity' value to 100%.
If that doesn't work, you could do an 'Object → Expand Appearance', which turns brush strokes into actual objects, which you can then individually edit to 100% trasparency.

I can suggest a method to make the cone, but I think the gradients will probably have to be created manually. I can't really think of a quick way of doing them. Sorry about that.
Anyway, here goes:
Select the circle and squish it into an oval
Copy it, paste in front, and group the copy
Hide the group
Use the Lasso Tool to select the middle anchors
This is for Illustrator
Draw a white filled square
Use the Mesh tool (U) to select a corner
Double click on the fill colour icon, choose a colour from the colour picker
Repeat steps 2 and 3 for each corner
There is a way where you can preview the design and see how it would look to a person with color blindness. There is an automatic way built inside the Adobe Illustrator CC 2020 (ver 24.0.2). Go to View > Proof Setup
